That's not quite what I meant, let me rephrase.
If you compare most of the MMOs especially those from Korea WoW doesn't have a grind focus at all. In fact, WoW has become very casual. I'm talking about the end-game. WoW original, TBC had a pretty heavy grind focus, I can still remember the days spending days, weeks, months at Tyr's Hand grinding the same mob to get a certain item/gold or PvP endlessly to get rank 14. WoW has changed a lot, you can get away with playing casually and still reach a decent level and obtain pretty much the best gear (in pvp at least).
I remember a friend told me about AION for example, it was pretty much just grinding and more grinding. Don't really like that playstyle, so I'm wondering about TERAs endgame!
