I like this idea. The charges would allow me to choose when I want to go in for a kill or when I want to proc my passive during a fight. The unit collision is a godsend and something that I think should have been on it from the beginning. And the evolution making all enemies isolated is really great, because in a team fight, unless their team separates and spreads, you are never gonna find an isolated target. Overall I think this would be a good idea, though it would def have to go though a lot of testing.
