Players will start from level 1 and will progress through level 60 with real, Blizzlike x1 rates. Old PvP battlegrounds are: Warsong Gulch, Arathi Basin and the famous 40vs40 players Alterac Valley where battles were known to last more than 24 hours. 20 and 40 man raids will be available for Molten Core, Zul Gurub, Blackwing Lair, Ahn'Qiraj 20 & 40 and the original Naxxramas raid in the Eastern Plaguelands.

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.
 ":"  -  Any time a step ends in a ":" instead of a "." means that the next step is part of the current step you are on.  This generally means the next step should be done while working on the current step.  This means every "start working on" or "continue working on" will end in a ":".  But this is used with other occasions as well, so keep this in mind. 

It is a great advantage to start making some silver and your first gold coin at low levels already. Skinning is a nice choice here. Fast and easy way to gather resources, leather of all kinds while leveling for those who are at the race to level 60. There are many good spots to grind beast mobs and skin them. I like doing it as a Troll Hunter, trolls have a passive racial ability: + 5% bonus damage against beasts.
Good question. Me personally, when I use a new strat from somebody else, I always read thru the strat, and in the case I really need to level some pet, I then (likely) exclude strats that are mentioning things like “RNG”, “risk”, etc. But: I’m always happy (when using a new strat) when I see some detailed infos, so that I can estimate what is going to happen. But YMMV.

Some even more advanced gold makers might also attempt to monopolize the market. It’s fairly easy if you have quite a bit of gold – just buy out every single item on which you want to have a monopoly on and then reintroduce it to the auction house with your new (and higher) price. However, it’s worth mentioning that monopolization tactic is risky business practice. But where’s high risk – there’s high profit.
2. Achieving. There are many pet battling achievements in game, and following the natural trail through the Taming [Continent] achievements up to Pandaria, and then on to the Spirit Tamers, Beasts of Fable and the Celestial Tournament was an epic journey for me and for many others. It's well worth doing. The Celestial Tournament is still, IMO, the pinnacle of PvE pet battling. However, WoD and Legion and BfA have added more battling achievements.

Where to get materials and reagents you may ask? Buy for cheap off farmers in bulk or track Auction House lots. Get in touch with most big sellers. Communication is important here, send a whisper or write them a letter. It would be good for both of you to establish business relationships. Constant suppliers and buyers is convenient for both parties to save the time and effort.

All of this is keeping with the spirit of vanilla, which I think is more important than that a specific number be 11 instead of 12. And it would help to "resize the swing" by making the game harder to the more experienced community, and forcing people to re-discover the game rather than simply looking up whatever they want to know on a spreadsheet somewhere.
The fact that Cookie's Tenderizer from the Deadmines had +3 instead of +2 strength. The fact that the Stormwind south bank had one instead of two mailboxes. The fact that Jaina's Proudmore's name was "Jaina Proudmore" instead of "Jaina Proudless." Stuff like this isn't what mattered. It was arbitrary. If Cookie had dropped a shield instead of a mace and Jaina had been named Susan, nobody would have cared. It wasn't specific details like these that caused us to enjoy the game.
Sorry! No addons (unless some are made specifically for the new release of Warcraft Classic). Also, Bidding Is A Thing.  There were bidding wars for the most expensive items on the AH, which you can only find in IF and Org. There might be bidding wars for the rarest of items on trade chat or the realm forums, for things such as the Hide of the Wild pattern. This drops from Dire Maul, Knot Thimblejack, by the way.
While this might be a change for the better,leveling in Classic will most certainly be different than leveling in Vanilla. In addition to sharding making the beginner zones much more friendly to the hordes and hordes of players storming the gates when Classic comes out, theVanilla leveling process has been studied thoroughly since the game came out 14years ago. Since then, not only have players leveled multiple alts and characters through the beginning zones in Vanilla, but they have done so on a multitude of private servers intended to have the most ‘Blizzlike’ experience. So while leveling a character from 1 to 60 will still be a long, arduous process, it will no longer be marred by mistakes made by players going from zone to zone, continent to continent, searching desperately for a place to level. The zones and routes have been thoroughly mapped out by the Vanilla WoW community at large, and with the internet being much more robust in 2019, that information is just a google search away. Is that a bad thing? I would venture to say that it isn’t, as knowing where to go and what to do doesn’t make it any less challenging and time consuming. It does take away from that exploration aspect,however. You might not have those moments of wandering into Feralas for the first time, or running from Storm wind to Strangle thorn just for the hell of it,or getting lost trying to get to Iron forge from Darnassus on a fresh Night elf.No, those moments, just like many fond memories of Vanilla, are lost in time.
Mounts also take up space in your bags, bags which will of course be much smaller.  Every bag space counts.  With no guild banks, and much smaller storage space, your bank alts are going to be essential.  You’ll need to remember to always post everything back to a bank alt, and to remember to get everything from the mail box to the Auction House.  Which is only in Ironforge or Orgrimmar.
You will have to talk with flight masters in most towns or cities you visit in order to gain access to that settlement's flight path. Flight masters who have a stop you have not yet unlocked will have a green displayed above their head (and on the mini map), much like a NPC with a quest. Unlocking flight paths as you progress through various zones will allow you to pay for a quick ride to a destination you have previously visited. This method of travel is significantly faster than walking or riding a mount.
FYI: If you’re returning to WoW after an extended absence prior to patch 5.0.1, it’s possible that you’ll have more than the maximum pet limit and/or more than 3 of a kind. However, this will be the only time that you’re allowed to surpass these limits. You will have to pare down your collection, eliminating your duplicates, in order to add new pets.
