Before Riot nerfed his Q and changed his passive so that you get a lot of sustain from it early, along with being able to buy Vamp scepter, WW was looked at as FoTM, and rightfully so. He outsustained everything you did to him, and he was super good against even multiple enemy champions.

Now, what do we have? A tanky bruiser whose only damage source now is his Ultimate, which makes him weak pre-6. If they had reverted the Q back to what it was, though, along with upping his passive, then maybe he'd be good again.
