I'm not saying zeds op, because I do not think he is but...
but the way zed works makes the person playing him look super high skill even when they are not. He litterally works like this, he hits R on you, he throws his W, Q and E, you get hit by the E dodge one of the two Qs flying at you, the other hits. He proceeds to auto you once and hit R again returning to his original postion. That Q, E and auto did enough damage to make his ult basically kill you, and then badaboom dusk blade pops finishing you off. the Zed then spams laugh as if he did something super high skill cap. The zed proceeds to lose the game because "his team was trash" even though we all know zed can't carry. TL:DR zeds a dumb champ that really doesn't take that much skill to assassinate a squishy but can't carry worth shit.
