I like another dance, a 3 step one that does huge burst dmg like the others but causes debuffs to go on anything hit, I'd think 10% reduction in damage dealt, be on a 180s cd so keeps busy work as low as possible after opener to every 6 mins in a fight.

Sabre Dance to be ogcd.

Closed position available at level 50 at the latest(love if level 15 but May just be even more overkill)

Personally I'd like to lean more on dancer having debuffs but not DoTs going forward I think as a buffer we are very solid

Obviously anything added to dancer would result in Brd and Mch getting an equivalent type of skill or flat out more damage as compensation.
