And I believe that a lot of the people who say that are lying for the sake of lying. You cannot tell me you enjoy logging in for the 150th time and thinking "Ok, I'm gonna re-do the same daily quests on 1 or more characters today, then do the same raids for the 20th time today, then farm some rare world boss for some rare item for the 200th time."
If they tell me they log in for PVP I'll give them the benefit of the doubt, since for 5$/month I'd return for PVP as well, although like I said, it would be a love-hate relationship even then.
