I'm leveling alts. I realize I could do alt classes on the same character, but I like experiencing the MSQ again - it's a bit like revisiting an old friend. Not to mention, by the time I get to 60, I'll be sitting pretty on a couple million Gil from quests and daily roulette awards.

I might also at some point see if there are any oddballs out there who would want to try using classes to try and run content with, instead of jobs, just for kicks and giggles. I'm one of those who actually really likes the class system and how it's implemented, and I wish they'd do more with it.
