That's a fundamentally stupid thing to say.
I liked WoW from TBC up until Cata. Then the game changed in ways I did not like, so I quit.
I did not suddenly say "Fock, I'm goddamn tired of these MMO games, I've had enough". No, I quit WoW, after having a blast playing it for more than 4,5 years. It's the decisions that the company made that made me abandon it.
So a newly launched MMO similar in basics to the pre-Cata WoW in a new lore package is something I'm looking forward to immensely.
