There's a lot of bothersome things about the Duty Finder that can't be helped. There is one convenience that to be in the developers control... here it is...

Have the duty finder save your "Gear Set" upon registration. That way players won't have to worry about missing the queue due to the "few" clicks. I've also noticed some behaviour in the DF that suggests that people register and disband quickly and repeatedly; presumably to troll other players. If the gear switch didn't happen until entry, there would be no GP waste.

Programming-wise... it seems like an easy enough to implement. Please consider it.
