Zed jungle??

As quoted from the league wiki:

"Zed's ganking and pursuit power also makes him an ideal jungler. Switching places with your shadow clone via Living Shadow creates opportunities for lightning-fast initiations, escapes, and even buff steals. The powerful slow from a cloned Shadow Slash can also lock down an enemy champion, leaving them vulnerable to execution from a heavy hitting attack charged with Contempt for the Weak. "

So if he has all these positives- what keeps him from being played jungle? I've seen things like energy management issues and a bad clear in comparison to others- but other than the fact that he's more suited as a lane bully, why isn't he a jungler?
