Allow armor to decrease knockup/knockback duration/distance
Since tenacity does not affect knock ups and knock backs, I was thinking there should be a way to counter it.
My thoughts, if a character has lots of armor, technically, they would be heavier, making it harder to knock them up or back. I was thinking something like at 150 armor there is a 15% decrease in knock up duration/knock back distance and then at 200 armor there is a 35% decrease. In general, this won't benefit most players except for tanks, but allows for some way to counter stuff. (imagine a Lee Sin kick only knocking back the tank half way so he doesn't actually hit the rest of the team)
