Zed's appearing possition from his ult should work like Katarina's shunpo ability.
Zed's ultimate nerf(0.5 delay for him to swap with his shadow) hurt a lot of zed players since we lost a way to use our ultimate more defensively, but it was an arguably necessary balance change. the thing is that nowadays Zed is way more predictable than he used to be, and if you ult at a wrong time you will get either CC-locked to death by a Lissandra ult
or charmed by an Ahri inmediatly
because you will always appear behind her for example, and a lot of time you will not even consider ulting if your W is not up, since you wont kill the target neither will you survive, leaving you feeling powerless.
So i suggest that we make Zed's appearing possition from his ult work like katarina's
shunpo ability, meaning that Zed can choose where he will appear when he ults(a specific area around his target), this way Zed can be a little more umpredictable while still giving the enemy team a good window of opportunity to respond.
that rely on casting abilities behind themselves to snare Zed.
