AAA means only one thing - An Aggressive Advertisement. "Ensures quality of product"? Lol... If it would be true, I wouldn't be playing WOD now. I personally don't see anything, Wow has, and some other MMO don't have, that worth $15 a month. Every freakin MMO has something to make me log in and play for a hour every day. In order to be worth $15 a month - this game should offer something special.
Paying sub fee = investing money into future of this game. And for me investing into future = investing into new content, I personally like. But when game developer all of a sudden decides, that he no longer should create content for me, cuz some other players are more valuable for him - then he no longer deserves my money, cuz such game has no future for me. Such game can only be free.
