I think Zed would've been cooler if...

I think he would've been cooler where when he ults, he goes into shadow portal (his backing animation) thing, making him invincible, invisible and untargetable (just completely off the map) and creates a zone around his target. He then is able to create shadows around the target using W and R, available to swap and reappears out of shadow portal thing when a shadow is swapped, and the target just takes extra some damage from his auto/skills, or skills only. I just heard about assassin rework and thought about what I'd want to do to him. I feel like this could put in "surprise I'm a shadow ninja lurking in shadows for that booty bae bee" type of aspect to him, also reinforces the rivarly with Shen, if Shen can shield and save a champ out of no where, Zed can appear out of no where and attempt to kill a champ. cool idea no ? lol
