What I mean to say is that the nerf to his W hit his performance botlane hard enough that he really doesn't do anything better than any other ADC. However, in mid lane the attack speed debuff is a lot less potent, and they actually buffed his ratios, so from what I've seen AP Ez actually brings more to a team than AD these days. His old role as an ADC was early lane dominance and security and now he simply has little place as a bot laner. (All my opinion of course, and this is not to say he can't deal damage and be useful as an ADC.)
