[@NarcissisticPotato] pretty much. Her main weaknesses would be basically using no armor, only clothes (she would be severely impaired in her mobility if she used any armor)
And the fact that her dances draw aggro. Although she performs her dances with her weapon, her attacks while dancing are 50% weaker due to the fact that she needs to pay more attention to her dance than her attacks.

Any dances used are an active buff. Once she stops dancing, the effect it gives to enemies/Allies is gone.

So basically she has 2 modes: an rogue\dps mode and an buffer/de buffer/caster mode. Needless to say, her play style changes drastically.
