I know the ability cant defeat her so there are times you can't use it. Is there also a max amount of times used as well? I got to a point in t6 of her event where I couldn't use the ability at all even with plenty of health. Also feel like I should've had more whirlwind to use too but can't prove that. Only time I seemed to be able to use that was once each when rey and Finn went into immunity damage. Not when rey kept cycling back and forth or holdo or 3p0 dropping.
