What if, instead of pointing and clicking... you had to draw out your path in the form of a skillshot before releasing, hitting enemies along your path after release? You'd get x amount of maximum length and you'd be free to draw that length out in whatever shape you saw fit. Once you drew out all the length, you'd launch the skillshot. On second cast, in the middle of your route, you'd choose a spot along that route to reappear at when Yi reaches the end of his path.
Feels like that would be more interactive than just "I press Q, I hit everything and avoid all the bad." I don't see any glaring flaws with it, except that people would probably try to draw genitals as well as they could.
