What about a Stance toggle like Love dance, wich make the enemies Damage 10% of the damage they going to make against you and you recive 10% more defense while lossing 20% power or anithing new like, you are dacing so lets make all your GCD .30 secs longer? so you can let the dancer with low atack power with the stance but cover the diference with that and that 10% damage "reflection"

And other types of dances wich creates distraction to the nemies and bosses, like Flank dance, make the enemies at 5 yalms of distance take more damage for Flank position, and rear Dance for more damage for Rear, these effects can't use together and drain your mp in use (or maybe can use together but the MP drain its faster?). That can be cool xD
