This is a super "cool" mechanic! I think there's a lot to be improved but this could be truly great, the potential is very high imo. I'm imagining something that feels similar to pulling off Irelia's Q (from League of Legends) on a bunch of minions.
I think it needs to be clearer which enemy I'm going to dash to, a few times I'd have two in range and the game would choose the enemy that would kill me.
I think with the RNG tuned and more juice this could be awesome.
