While our initial effort helped us determine the experience we wanted to provide, this second prototype really defined how we’d get there. Starting from a modern architecture—with all its security and stability changes—means the team’s efforts can be focused on pursuing an authentic classic experience. Any differences in behavior between our development builds and the patch 1.12 reference can be systematically cataloged and corrected, while still operating from a foundation that’s stable and secure.
In-game mail between guildmates now is instant, but in the past, it had a 1-hour delay, just like mail between strangers. The change to instant mail made things more convenient, but removed the social interaction of having to meet up with someone to make a transaction if you wanted something sooner. So we’ve reintroduced that delay for that reason. Other conveniences such as auto-completion of names or quickly clearing a mailbox have been left in. This seemed an easy enough call given that someone could create an add-on to do the very same thing, and we felt those sorts of conveniences didn’t impact the fundamental “classic” experience.
In this form, there is much less wasted space and spells are no longer limited to three effects. But before we can load any database data, we need to transform the old data layout into the new one. This is not limited to spells, as almost every game system (including items, creatures, player characters, spawning, AI, and more) has had its database layout altered over the years.

You're absolutely right! I've changed the opening—I hope it gives you and your list the credit you deserve. As for those other tools, I didn't include them originally because I didn't consider them to be class specific. I'll include the Base Stats Calculator here, plus add a message at the top directing people to your list if they want a more comprehensive index!

A demo of the game was available at BlizzCon 2018, and was downloadable on home computers for anyone who purchased a BlizzCon ticket or virtual ticket. The servers became available when Opening Ceremony started at BlizzCon 2018 and was set to end on November 8, but was extended until November 12.[4] Players started at level 15, and the only available zones were Westfall and the Barrens.[5] It was based on patch 1.13.0, essentially patch 1.12.0 ported to a modern infrastructure. The first day of the demo, there was a playtime limit of a cumulative 60 minutes with a cooldown of 90 minutes, applied through the BlizzCon Exhaustion debuff.[6] The debuff was removed on the second day of BlizzCon 2018.[7]
Our initial runs exposed a few (expected) issues: the game sometimes crashed, didn’t recognize our modern video cards, and was incompatible with our current login system. That first pass also couldn’t support any of our modern security and anti-cheating capabilities. Clearly we had a lot of work to do to make WoW Classic live up to the Blizzard standard of quality, and deliver the experience players want.
Nov 15 How to fix paladin dps Just make holy wrath & exorcism work on all types of enemy but not affect player characters. It's an easy fix that will make pally dps better in pve but stay the same as they were in vanilla in pvp. Put this thing into a deep ret talent so it will require people to spec deep in ret to be able to dps. A good spot is add it with two-hand weapon specialization making it so that by putting talents into it all hostile aside from players and undeads(since they are already affected by the default version) to be affected by the dmg and effects of the spells effectiveness by 33%/66%/100%. I doubt they would even do this so im just throwing out ideas since too many of you dont actually read the forum and only read the OP here you go to explain a bit of my reasoning because this change wont make ret stronger than pure dps; clearly most of you people didnt play vanilla nor know anything about naxx. ...Toushin260 Nov 15

Nov 15 Looking Forward. So simple fun thread to see how you all think and feel. Name 1 thing you are definitely looking forward to, preferably not the obvious stuff but whatever go wild! I'll start with one. Professions aiding in immersion. Not sure if many noticed this but something I am excited about playing a hunter is the professions and how they aid in immersion for the hunter class so freaking well. All of the secondary profs help hunter immersion. Cooking, Fishing and First Aid all actually fueled the hunter lifestyle. Add in Skinning and Leather Working and it's straight up Hunter RPG.Melaned22 Nov 15
I hate to be the one to say this, but let’s face it: we’re not little kids any more. Even for those of us who played Vanilla when they were well into their adult years will have gotten 14 years older, 14 years wiser, and up to 14 years more experienced with video games. What does that mean for Classic WoW? Well for starters, the grand majority of people who are interested in Classic will now have full time jobs. Some might have families and kids they didn’t have before. Basically, WoW Classic won’t be a big of a chunk in people’s lives as it was back then. Considering how much time you will really need to put into Classic WoW to enjoy everything it has to offer, that might be an issue. Stringing together 40-odd people to storm Blackwing Lair might be significantly more difficult now than it was back then. However, due to the issues I talked about in the paragraph above, it might not need to be the long, arduous hours that many people put into Vanilla raiding. With the right preparation and knowledge, raids in Classic will most likely take considerably less time to complete than they did in Vanilla, which will hopefully counteract the fact that the majority of players will have less overall time and fewer long chunks of time to play. 6. Conclusion In essence, the game itself might not be changing from Vanilla to Classic WoW, but the knowledge and mindset of the players of the game will considerably change the way the game feels. Everyone probably figures that there won’t be that same sense of wonder that Vanilla WoW brought so long ago, and that’s true. Nostalgia can only carry Classic WoW so far. Thankfully, I believe that there is some truly solid game design inVanilla WoW, and the fact that Blizzard have doubled down on creating a verbatim experience for Classic WoW is something that people have been adamant about since the day they announced its release. Only time will tell if ClassicWoW truly is the thing people have been wanting, or whether the new CEO ofBlizzard Jay Allen Brack was right – we thought we wanted it, but we didn’t.
Nov 15 Question about the PVP system I am struggling to put the words to my question so let me just throw my 'plan' out there. Please correct me if my assumptions are wrong. Since horde are typically the pvp focused faction, I planned on rolling alliance on a pvp server with horde dominating the server in order to climb pvp ranks easier. My queue times would be instant and there would be less competition when trying to climb the ranks. The way I understand the honor system is that I am competing against others on my faction for a position on the ladder. Less competition would make it easier to climb. I know I will never get rank 14 and don't plan on it. I thought with my limited play time, if I was on a horde dominated pvp server I would cap around rank 6-7. Being on the alliance on the same realm I could get to 8-9 with the same /played. Is this true or do I have it wrong?Jdpp5 Nov 15

As it had been executed in Vanilla, Can Blizz launch the PvP rank system? As somebody who was wow classic gold around back then, and without needing to get overly hand-wringy, I feel that the position system itself supported some fairly unhealthy behaviors. That top rank took months of continuous grinding, and I mean constant, 10 to 12 hours each day, to the stage where people weren’t even functioning properly and everything out of that honor grind was excluded. There were things in WoW Classic that you had to forfeit your wellbeing and life outside of WoW Classic to obtain.

Making "new" guides seems kinda out of place. Not only is there still alot of information from back then available, there came alot of information up for minmaxing available for both leveling and raiding, ontop of various bis gear lists that cover patch progression aswell if necessary. Wether people like or dislike pservers does not make the various information found on their forums less valuable.
After this past year of working on this project and forging our way through the various bugs and challenges, one consistent theme that’s emerged is that the difference between what we have and what we want is clearly visible. When we look at today’s World of Warcraft, we can see the differences between the modern game and the classic one. If we tried to update the reference client, we would have instead been tracking down a lot of “invisible” changes such as exploits waiting to be abused, crashes that don’t show up until you have millions of players online at once, and more. We chose to approach the problem in a way that makes our job clear and obvious instead of difficult and hard to see. 
Nov 15 My only complain about Classic... ...Horde doesn't have any nice looking races. In my mind each class has best RPG based race for it. So, I like Gnomes because I feel them Mages. Night Elves - Hunters. Humans - Paladins. On Horde side: Undead - ugly. Trolls - ugly. Orcs... uhh fine as Warriors, but I don't play warriors. Tauren - Warriors or Shaman, again don't play those. Blood Elves! Give me Blood Elves!Vlasta36	Nov 15

File data: This is often very dense data like 3D models, textures, animations and terrain. Our user interface is built up from XML and Lua files. Many of the art files do not use the same file formats that commercial art tools spit out. Our build pipeline takes these raw art files and translates them into something optimized for our game to read and process.
Finally, a clip of WoD: https://www.youtube.com/watch?v=YtKDmlNLVtE&t=5m26s This one I have petattack macroed to a button on the right-side action bar, 2nd from the top left side (icon looks like a bone bow). You can see my bird pet take off INSTANTLY when pressed. I realize this one doesn't prove much regarding Classic, but this is proof that it WAS functioning this fast until Legion. You can see the delay on Live yourself by logging into BFA.
Even though a modern server architecture is used, Classic servers won't have the same features that current World of Warcraft does. There won't be cross-realm servers or Looking For Raid and Dungeon Finder automatic party matchmaking. There are still a lot of questions about how the team will tackle it. This endeavor is being undertaken by an entirely separate team at Blizzard from the one working on World of Warcraft and its next expansion.[2]
For another example of lighting, we looked at Elwynn Forest. We had a period in Warcraft’s history where we changed all the lighting equations and as a result, our environment artists had to take a pass over all of the zones to improve the lighting and take advantage of the new equations. To recreate the original experience, we had to rewind those changes. The first thing we did was restore the old lighting data. This brought us much closer to the original lighting—and with a few more changes to the distance formula, fog formulas, and some changes to shadows, we were able to bring things even closer to the original lighting.
