WoW got so big and popular it began attracting a large number of players who totally hated many of its core gameplay elements. I hear it over and over again "I HATE leveling. I HATE questing. I HATE exploration. I HATE having to interact. I HATE having scheduled raids."
How does someone with those gaming preferences ever find a game like WoW?
Over the past few years the game has evolved to cater to this crowd and as such WoW is basically morphed into a different genre game than it was 4-5 years ago.
This would be like me joining a motorcyclists club even though I hate motorcycles and actually like dunebuggies, so I do everything I can to convince everyone to convert all the motorcycles to dunebuggies.
I mean, wouldn't everyone be better off if I just never joined to begin with?
Quite the irony that WoW's greatness and popularity are also what ultimately led to it being in the state it's in today.
