I was thinking of a DPS that was also an off tank and off support. Dancers would be able to tank single enemies by inflicting a debuff that made their next attack miss. It would be part of their regular rotation, perhaps toggled with a stance skill so they could choose a more dps oriented style of attack if it was more appropriate. They would also have dances that would be aoe buffs/heals, but not as strong as a healer.
