I'd be very interested in some sort of challenge. In fact, I'd be up for just about any challenge, as they seem to get me over my hangups about continuing with less than perfectly rolled characters
EDIT: I second any sort of team competition. Solo challenges are not NEARLY as fun (half the fun of the TWL '08 for me was the inter-league rivalry, specifically the Gut vs. Grey head-to-head! We should totally have them do some sort of 1v1 challenge consecutively, hehe). So again, Team challenges for the win.
Normal - GE Ranger, Human Monk, GE Wizard, Hurthling Beastfighter, Hurthling Farmer
Ultra - ULE GE Wizard
