Rengar's Ult/Leap
I think Rengar should not be able to use abilities while he is in ult, I've played a lot of Rengar lately and it feels really clunky when you're about to jump on the carry in a teamfight, and they move right when you get in range and you end up cancelling it with your q. Then you lose the game because of it. And I know Rengar is very strong right now, so I think he needs nerfs, BUT, as a clarity thing, it should be changed in my opinion.
