I 100% agree. If I could trade my rey and resistance for a 75% return and put it all towards getting kylo, I would. Even if that 75% return didnt include ultimate materials or event tickets and I had to re-do that. That's how disappointed I am with Rey atm.
If they made her team immune to critical while in ultimate, and gave her better stacking mastery to allow her to also solo HSTR, I'd change my mind. Or allow her ultimate to recharge while in ultimate form so that she could more easily chain ults (and make DN annihilate only do 1 damage in the raid to someone in ultimate protection).
