it doesnt have to be completely unique, only somewhat unique :P, something you dont see every week. so a 12/7/1 mnk/rogue/rgr, that looks like plenty of healthy DPS. a 12/6/2 ftr/rgr/mnk kensai AA is good dps. a 7/7/6 ftr/rgr/barb looks to be decent dps
all of these you dont see often, all of these fine dps i think
