I think a quality fair amount would be about 1,000-1,500 exp, too high and it undermines the grind, but it's def. too low right now IMO. But I'd like some variety, like maybe give me a reason to go after a melee class for once! Or at the very least something that gives me mini-victories as it slows down when I rank up.

I would accept the same boring challenge log though if it was a daily :P.
