As of right now, there is no official exact release date, aside from confirmation of summer 2019. It is expected to hit the internet roughly mid-July, or possibly in August. Something as highly anticipated as WoW Classic could launch with weeks of notice and still break records. As of April 21st 2019, World of Warcraft Classic has entered internal employee alpha testing.
Nov 15 5 reasons I'm doubtful of WoW Classic I played WoW from patch 1.4 until Sunwell. And I'm not convinced on Classic. 1. I understand nostalgia for the gameplay, and it was a great game, by I don't get why people would want the old graphics when it looked outdated back then. Someone will level a warrior or rogue at snail pace and those 2004 boring graphics will reinforce his perception that the game is bad because it looks bad. 2. The lack of a second talent tree. This was the most demanded feature and I don't see people sticking with the game without it. 3. This has always been in the game, but weekly resets, I never got it, let people able to reset raids. Maybe have a 2 hours cooldown, but if a guild wants to farm a raid every night, or twice on a sunday, or farm the first 3 bosses of MC, let them. Gearing 40-60 people with weekly resets, in this day and age, good luck. 4. Dungeon finder, not sure people will like that, again bad decision. 5. The graphics, no seriously, this is bad on every level of game design, it just make the game look worse, a straight negative with no benefit.Pekuakami24 Nov 15
My main plan will be to focus on raw gold in the beginning. Then I will spend my gold on leveling tailoring and enchanting so I can shuffle enchanting materials which is likely to be very profitable. I already have some shuffle ideas, and I will look for more. Then I’ll work on obtaining the rare enchanting and tailoring recipes to craft those for gold. 
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

Why Skinning? Skinning is incredibly easy to level up while you are leveling your character. The leather that you skin will almost always sell on the Auction House (albeit not for much, but hey– it’s free gold!). Even if you don’t want to take the effort to sell the skins on the Auction House, you can simply vendor them for a significant amount of extra gold.
Nov 15 Thank you for the demo I just want to say thank you to Blizzard for the demo. I seriously had so much fun - so much more fun than I've had trying to play wow in YEARS. I know not everything was 100% accurate to classic, but it was just a demo so that doesn't worry me too much. I still had a million times more fun playing that demo than retail in any case. THE THINGS I LOVED: (1) I died so much. Like... SO MUCH, and that's alright! Once I finally finished whatever it was I was doing, it felt really rewarding! My group and I were actually laughing when we party wiped. No one insulted anyone or pointed blame, we just had fun. (2) Things took time. The journey mattered, it wasn't just about hitting end game asap. I felt accomplished at the end of all those time consuming things I did. (3) I had fun exploring! I spent so much time just running around, not knowing what the heck to do, but that was FUN. I had FUN getting lost and finding treasure chests. (4) Seeing the classic models again! Tbh, the races all look rubbery and stupid now... I honestly think the old racial looks are nicer. (5) Reading quests was necessary again, so the story mattered to me. No one booted me from the party for "taking too long" because I wanted to read. (6) The community! There were actually people doing RP stuff and talking in character. Everyone in the chat was just having fun. (7) All of the inconveniences - running out of mana, no mounts, running slowly on foot, little or no flightpaths... These things are fun because they're not just handed to me. I had to work hard and play the game to get things. (8) People constantly buffed other players, because that small boost could be the reason you didn't die when a roaming centaur attacked you from behind. THE THINGS I WAS CONCERNED ABOUT: (1) I've heard rumors about possible sharding... PLEASE DO NOT SHARD. PLEASE. I can understand if it's temporary just for the initial launch, and only for starting zones. I think that is a decent enough compromise for the inevitable problem of overpopulation for the first few weeks. But if we're talking about full scale realm sharding, PLEASE DO NOT! Cross-realm features and sharding are what ruined communities in wow, same with dungeon finder and other such things, and these features are very unwanted for a classic player like me. (2) The elite raptor I tamed as a hunter was not stronger than the non-elite raptor I tamed at the same level. In classic, elite animals had better stats as hunter pets once tamed, compared to the same non-elite version of that animal at the same level. (3) I think the mana and health regen rates were a bit too high? I'm not certain, but if they were I honestly want them to be genuine. It's okay if it's hard - challenges make games fun! Anyway, thank you again! I had a ton of fun, and as long as classic is true to classic with all of its pros AND cons, I feel certain that it will be a success.Sarai10 Nov 15

So we asked ourselves, would it still be possible to deliver an authentic classic experience if we took our modern code, with all its back-end improvements and changes, and used it to process the Patch 1.12 game data? While that might seem counterintuitive, this would inherently include classic systems like skill ranks, old quests and terrain, talents, and so on, while later features like Transmog and Achievements would effectively not exist because they were entirely absent from the data. After weeks of R&D, experimentation, and prototyping, we were confident we could deliver the classic WoW content and gameplay without sacrificing the literally millions of hours put in to back-end development over the past 13 years.

There is an Action Bar at bottom of the User interface. Each class starts with some skills. Every few levels, you will unlock new skills specific to your character class, these can be learned from your Class trainer. You will be introduced to one of these NPCs during one of the first few quests you complete in your starting zone, but they can also be found in many towns and each of your Faction's cities.
