You can be disappointed in something and still enjoy it. And your significant portion part is absolutely irrelevant. Why should a PvP'er have to enjoy PvE? Because that's what you're replying to a discussion where I'm saying that WoW can still be for PvP'ers even if they don't enjoy PvE. Most may play this game for the PvE, but the two are separate.
And, without fail, the dismissive "Quit or shutup" argument. People used that at 12m subs and they're using it again now when it's lower. Also, to repeat myself: You can be disappointed in something and still enjoy it. Why quit if I still get enjoyment out of the game?
I hate leveling in this game. It's beyond mediocre imo. Yet if I made a thread asking for changes, the same threads that have been made before regarding leveling, there'd be that one guy (at least one) telling me "WoW isn't for you". Yes, WoW isn't for me despite me enjoying it's endgame PvE and PvP (usually), simply because I don't like leveling.
Funny thing is, for all of the people who would tell me that, Blizzard ended up adding a way to skip the large bulk of leveling. It's almost as if that phrase is absolutely meaningless due to it's overuse by fanboys. I guess WoW is for me and not for them, considering they didn't want that, right?
