That its an mmoRPG…not a “MMO Lobby Simulator” with RPG elements sprinkled on for #@$%S and giggles. That classes are different and unique, that it doesn’t hold your hand instead it makes you go out into the world and make it your own experience.
I’m just looking forward to going back home, x-pacs are all well and good just never liked the gear resets,play style resets , the constant buffs/nerfs the never ending game of trying to make all things “equal” or “fair” cause some people in the community want a pony if Johnny has a pony and if they don’t get a god damn pony they’ll quit and walk away. 
Also looking forward to base game because IMO its the closest to what they originally wanted to do with the game. Its crazy to go back and watch youtube vids of the first few blizzcons and how much their philosophy has changed with the success of the game.
