I had an idea about jumps...
What if we split jumps into two things, jumps and leaps. I thought of this because of the different jump animations and the ability to cc someone who is so very high in the air. Jumps: During the jump animation, you are immune to root, stun (until you hit the ground), snares, and knockups. Possibly knockbacks. Leaps aren't immune to anything. For example, Rengar's low to the ground jump looks more like he's leaping, and looks like someone could still knock him up, but kha'zix is a different story. He Literally soars over everyone. And I was thinking that this could add more depth to the ability to nerf or buff a jump. Tristana's ever get to powerful? Make it a leap. Although there would have to be different animations made, possibly in that Leaps would have to be lower to the ground than jumps are. But I don't know.
