I guess some people just don't understand that the game was ruined once already with lame expansions that did nothing but dumb the game down to a minimalist game with no direction, no need to explore or do professions
Yeah but that didn't happen until Warlords :)
Anything other than moving on to TBC would be controversial for the same reason sticking dual-spec in Classic would have been controversial. We could never agree on anything else and that is the status quo.
I expect to ride this train all the way to Arthas then get off again. My time in WoW was fantastic so I'm fine with doing it again, especially now I know how long it will take. I don't want to play WoW forever; part of the WoW experience is the blessed relief you feel when you finally quit.
