Why doesn't knock up stop Jarvan's dash?
I get brain damage every time I'm playing Vel'koz and I pog flip Jarvan mid-dash, only to have it not actually do anything to him, followed by him ulting me for an amazing zero counter play kill from 1500 range.
This makes zero sense. There's no reason to not treat this ability like any other dash, especially considering how absurd his engage range already is.
