You could say that about pretty much any MMO. There are the players that don't mind the grind and might do different things each time. And there are those who despise any sort of grind whatsoever and just want to get to the max level as quickly as possible. I played WoW for a year and there's always players moaning about the grind to 80, because that's all they want to do, hit 80.
Having this option won't introduce that as it's already there, it's inevitable with an MMO.
