Can we please give Zed some sort of change?

Zed is more annoying than Teemo. Unlike our satanic rat, Zed has more mobility, a dash that makes him untargetable and he can swap with his shadows. That doesn't sound so awesome, but when you consider that Zed can use this swap every 10 or so seconds, that makes him the most mobile champion. Using his ult, he can easily engage on a target and kill them, then he can swap to safety with his ult's shadow, completely out of the fight. I'm not saying to reduce his damage. He's an assassin and should be able to get a kill. However, I believe he should be knocked down to the level of those assassins such as Talon, Ahri, and Teemo. They have to wait to get their targets and think strategically. Zed only has to wait out crowd control and then Death Mark his target. When he finishes going ham on that target in the 0.3 seconds that it takes, everyone now is focusing him. But sadly he can just swap with his shadow which is OUT OF THE FIGHT. Meaning he can safely jump in, get a kill and jump out without any cost what so ever.

My proposition is Riot put a 1.5 second cool down between him casting Living Shadow and then swapping, with the cool down increasing by an additional 1 second if he is in battle. For his ultimate, it should be put where it used to be before the patch long ago. Behind his death mark target. This will allow him to power spike, but disallow him from escaping a fight so easily and require him to think about where his target is.

TLDR: There is a reason why everyone hates Zed. However his state cannot be fixed with number changes.
