Rocket Jump

So, I play a lot of Tristana. And while I'd like to say my mechanics with her are pretty good, there is one counter-intuitive aspect to her kit that routinely leads to frustrations with me: her rocket jump. Needless, to say, Rocket Jump is a cornerstone if Trist's kit, allowing her a good escape tool as well as amazing mop-up potential. However, there is one quirk to it that flies in the face of all conventional logic: Tristana can be CC'd, melee attacked, and hit with just about everything else, mid rocket jump. Call me crazy, but I don't think Cho'Gath's Rupture should effect me while I'm 20 feet in the air (how does one get knocked up when they're already airborne?) Perhaps this wouldn't bother me as much if Fizz didn't get immunity to everything for an entire year by standing on top of a trident, but that's besides the point. I think if our beloved Yordle gunner is able to soar over walls and trees, she should also be able to hop over Miasmas and Enchanted Crystal Arrows to her little heart's content.
