Zed

What is the argument for keeping Zed's power level?

He has a very dominant laning phase since lv 2, Which makes little sense for an assasin, as they are supposed to be weak very early on so the lane opponent, often a squishy mage, has time to farm and obtain 1 survival item. Why is there a design exception for Zed?

He is one the most mobile champions in the game, probably just behind Lee Sin and Nidalee, but unlike most Assasins who are also very mobile, Zed's mobility can be used both offensively and defensively, with no real cost but a cooldown bound to it. Assasins often have to pay something big in order to have big escapes, Why is Zed an exception to the rule?

All assasins have a dificult time, atleast early on, farming minion waves, It's supposed to be like that, they should be farming kills not CS, why is Zed allowed to do both?

Every single "bigdangerability" in this game has large, colorfoul indicators in them, why are Zed's shadows, abilities, clones, and moves so dark? I get It's shadow themed but clarity should prevail.

Why is Zed over almost all design staples this game follows?
