@Ink - It would be pretty damn hard to argue that properly using a spell is considered an exploit :P
@Gandalf - I don't think I'd trade mages with someone in a duel. Actually I don't think anyone would, what's the gain in trading with the only other player on the map? Your definition of duel is a bit odd
. I'm sure that in a RAND game that would be considered cheating, but I don't think there's any other game type where that would be considered an exploit.
