If Zed has his ultimate, he has the potential to do more single target damage then anyone else in the game. Hit ALL 3 Q's , + W + AAs. wargmogs + BC +BT + The passive of his W? Its not uncommon to see a 3-4 item Zed, with one item being warmogs, to have 300-400 AD. He isn't really lacking, IMO armor needs to be buffed, and health de-buffed. In the 3 patch , the simultaneous buffing of Apen and nerfing of armor destabilized the game (again IMO). I think we will just have to wait a month or two and see how everything settles.
