This champion look like she could be a lot of fun. She looks like she would be a really solid solo top, with her passive that give her stacking life regen, her lunge ability will be a great gap closer for ganks and maybe to get away if the ability is a skill shot, and what looks to be the best steroid ability in the game with here Burst of Speed ability. Her ulti reminds me of Master Yi's Alpha strike, this annoys me, I think that riot is making to many champions because there is only so many different ways to make balanced skills and they should work more on balancing rather then a new champ every-other weekend but that's just my thought. Overall I think she has a good kit to dominate top lane and maybe jungle.
