Interesting Peter tech

Basically the speed boost from Swift transfers into Peter's ult and makes it move twice as fast. The result is it travelling 30-40% farther and more importantly being much harder to react to. It's surprisingly useful for taking back points in modes like dominion or td, as it catches people off guard and hits them before they can jump out. You can't activate spells during an ult so you can't get the full duration of the effect unfortunately but I didn't do it optimally here and should be able to get more distance. This technically works on anyone who lets you control movement during their ult super armor, but Don Q is too slow during ult and Timun's ult doesn't really benifit from being able to go farther. (Proc might be able to do it too now now that I think about it.) How viable do yall think this is?
