The company has provided a list of the most commonly reported gameplay elements that Classic players are reporting as bugs, including warrior health regeneration rates, the lack of quick objectives and POI tracking on the map/minimap, the presence of a dot as the marker for completed quests on the minimap, fast running NPCs, and slow creature respawn rates (full list below).

One player said in a comment posted in response to the list, “Yeah people don’t realize the sheer enormity of game system evolution WoW has gone through since release. I’m not the biggest fan of BoA by any stretch, but I’ve played since closed beta vanilla, and I doubt I’ll be going back to classic. Leveling was painful. Experiencing these old systems once was enough.”
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.
I’m used to either wanting to play a game or not wanting to play a game. But WoW Classic… WoW Classic is different. Maybe I’m just falling victim to nostalgia. Maybe I’m conflating the people I played with in 2004-2006 with the game I played in 2004-2006. Nostalgia is a hugely powerful motivator, after all, and even us jaded reporters are susceptible to it. I’m not sure how I’m going to feel about stepping back into a game that was genuinely slower, jankier, and less well-balanced than the WoW that exists today. I do know I’m looking forward to it more than any other launch I expect this year. Some friends of mine have already started planning for a return. I’m going to join them. It’s annoying to find myself pulled back to a game version I genuinely don’t think is as good, in many ways, as what exists today — and yet, here I am.
Nov 15 Classic Box Cost Disappointed in the decision to bundle the subs and (at least for now) not have a separate Classic sub option. That said, can we at least get a separate box cost for access to classic? It would: - help alleviate temporary bloat and subsequent dead realms - servers would be more stable population-wise over time - remove the bulk of the need for sharding - give a solid idea of how many servers will be needed - allow blizzard to set up a separate classic forum for those with a monetary commitment - with a separate forum group, feedback would be limited to those with a vested interest The subs would still be bundled, but there would be a box cost, akin to what one would have to pay for BFA access. A very good to-the-point post from later on in this thread:... Another good post about how the current setup would necessitate sharding:... A decent (albeit short-term) alternative:...Brokenwind314 Nov 15
And once you had been performing so 10-12 hours a day for weeks on end the thought of that time you’d already sunk into it made it rather difficult to stop. Combine this with the fact that missing a single day could put you back a full week of progress and you’ve got some pretty bad mojo going on.It may be argued that the Vanilla PvP honor rating system attested a lot of the negative perceptions about the MMO scene and video game addiction generally at the time. IMO it would be an error to reinstate it.
Another hurdle we had to overcome was how to store and merge our data. World of Warcraft has multiple updates or patches in development at any one time, each in a different stage of development. If an art asset or terrain file is added to one patch, the system is designed so that it also automatically shows up in later patches. This meant that If we had simply inserted a new patch for WoW Classic into the current development environment, we would have overwritten things like the current broken dam in Loch Modan with the previous intact version—and as you can imagine, this would have caused issues for Battle for Azeroth.

Druid is one of the most versatile classes across all of World of Warcraft Classic. By picking Druid you will have plenty of options to choose from while leveling. However, in the end-game, most groups will expect you to heal, though, Feral and Balance druids are also very desirable for their Innervate and Rebirth abilities. Additionally, various animal forms will make traversing the world into quite an uncomplicated task.
Finally, a clip of WoD: 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.

Nov 15 The most hardcore thing you can do. In vanilla? I have a few things that could be it. Playing on a perma death PvP server and kill kel'thuzad. Without dying even once. Being able to kill a mage/rogue/warlock/pally in all BiS gear Soloing a high end dungeon boss like rivendare or dark master gandling. Leveling to 60 with no gear or weapons or pet of any kind. That is by far the most hardcore, life threatening thing you can do in vanilla wowHavell7 Nov 15
