I played spontaniously until MoP, of which I just played for a couple of hours during a free trial. The game just isn't that fun any longer, especially when there are better (matter of taste, of course) MMOs out already, like EVE Online, GW 2 and Planetside 2. But I got a Paladin to level 85 on the Defias Brotherhood-server. That community was one of the greatest I've ever seen.
I played the trial for a few minutes before deciding that it's just one massive enjoyable grind. It might of helped if I knew anything of the lore and had a few friends who played it but alas I did not. Not my kind of game.
I don't like to speak of my WoW history because when I look back I realize just how much time I wasted that, while it was a hell of a lot of fun the first 4 years, it brought me nothing but misery and really crushed my love for video gaming (that and 3 years of the horrible community of League of Legends).
I had a profile on there not too long ago, but I forgot the password to my profile, then when I went to battle.net to confirm it was me I'd forgotten my password there as well and it kicked me out....I really need to start writing down my passwords.
