wow, seems like a nicely done champ. lets take a closer look.
passive: nice, utility with ultimate. not bad, movement speed debuff is nice, although, if they are running away, I don't understand why they would attack so wouldn't you say the attack speed debuff is a little.... unnecessary?
q: a V shaped splash, interesting. this splash, did you mean like a cone or literally a V? like, enemies hit by the letter V are damaged, but they are not if they are in between?
w: nice. does it stack with the passive? if so, I think it might be too strong and should be toned down a touch.
e: cool, like cho's rupture without the slow.
r: interesting, a transform steroid type ability. also aoe damage and damage aura. looks like it should be fine. that damage cap, is that fully divided amongst enemy champs or is that max damage per champ?
overall: she seems highly focused on the cc, mainly slows, as well as on the utility of her ultimate. she can also deal without her ult until she hits a team fight. a little clarity on my part is needed, but still, a fine champion. nice work.
