As a champion that does take a certain kind of skill level to actually ~~be good~~ use her to her full potential, I don't think she really needs that much of a nerf.
I acknowledge in teamfights she can be deadly but there are SO many champions with silence, stuns, and knock ups/backs that she is easily dealt with and countered. Her ult honestly, is the only thing she has. Nerfing it makes her even less of a viable champion **because** her ult is all she has to be a threat. She can throw Qs and W/E away.
