To quit playing a game you have to actually have played in the first place and not just been in a perennial state of attempting to 'learn the controls'.
Also I'm getting fed up of bishes complaining about the game. What's done is done boys, 6.0 you speak of was 2013 and gotta move on. Every time I hear this negativity I actually feel upset for the devs/admins who've put time and effort (free of charge) into this project for you boys to slate them at every opportunity. If I can stop BMing them at every turn, I'm sure some of you lot can grow up and appreciate what they have done too (even if you do not agree with the adjustments made to the game). After all there have been more than a handful of times Blizz have changed BNet and the game has had some game breaking bugs (which were fixed pretty quickly by the devs). Even if you think the game is in a worst state than before, it's better having a game than a broken unplayable one.
