Good point bro. There is usually only 3 AD champs on mid lane played Yasuo, Talon and Zed. The thing is, Yasuo has pretty much weak early game compared how insane he scales to mid to late game and has some weak spots, Talon has a pretty much high kill potential early game, but also he can be poked to death, and when it comes to Zed he has everything, high kill potential after Level 3, after Level 6 even higher, he can be poked but also he has much more dodging potential then Talon, and he also scales great. Also when u mentioned Lissandra is maybe the best mage to pick vs Zed, but if you play saomething like Lux, Ahri, Syndra, Xerath, Ryze, Vel'koz etc...You are fucked up, you have to rush Zhonya's ASAP. That is the only possible way to at least not feed him. But still when you play vs Zed, pick Vlad, in my opinion his biggest counter, and I never had problems with Zed when I pick Vladimir. Also depending on your team comp, if u have AP top lane or jungle, you can pick Irelia, with armor in your rune stats and Ninja Tabi's, and damage reduction on your W, he can't do shiit. But yeah, unluckily he is countering most of the mages at this moment, and you play one of those mages, just prema ban him until some nerfs :)
