Make Zed's Ult Shorter and Shadow Disapear Quicker

So needs to hit all his abilities way faster to kill you, the time for his deathmark to pop is to long and makes so easy to play. His shadows (ult and w) shouldnt last as long as it is so it won't be used as a poking tool, but an escape/engage. It'll make him harder to play so enemies will be able to live if they dodge his abilities.
