No. The problem lies when people only have the exposure of WoW.
WoW stops being a game and becomes the genre itself. That's what has happened. Rift dealt with it. SWTOR is dealing with. Every themepark will deal with it. When the next game comes out that isn't similar to WoW, people will complain that it's not enough like WoW. Doesn't have addons like WoW. Doesn't have Arenas like WoW. Doesn't have a launcher like WoW. Doesn't have a website like WoW. Doesn't have a game designer with name Ghost in it like WoW. WoW WoW WoW WoW WoW.
What people are sick of, they want most. What's different must conform to the familiar.
