Knockups should be a purely visual effect, Tenacity should make you heavier

Edit: hooray for idiots downvoting me without explaining why it's a bad idea or understanding what the post is about!

I'm not saying add a weight system that arbitrarily favours big champions, I'm saying TENACITY SHOULD REDUCE KNOCKUPS AS IF YOU WERE HEAVIER AND THEREFORE CANNOT BE LIFTED AS HIGH

---

Things like bard being sent back home by blitzcrank, or tenacity not affecting knockups should be fixed

Knockups should have a specific duration, and the animation of flying upwards is played over the duration. Tenacity should make them heavier, going up less high.

Knockbacks are slightly more complicated, but basically tenacity should decrease the distance a champion is moved by an effect

Pulls are more complicated, maybe they should be the only exception to the rule since tenacity users like being in range of something to hit.
