Lightning Mage

So think this is something that isn't done right now in league and this is a quick run one something I like. He would be a battle mage/fighter, with short to mid-range abilities. He wants to be in the fray, shocking enemies.

Passive- Modifies his auto attacks, when attacking an enemy at 1-200 units his aa become a small cone, dealing damage to all enemies in range. from 201-500 his auto attacks are a line, fairly narrow, dealing damage to all enemies it passives through. Probably deal reduce damage overall since all his autos are aoe.

Q- 325 range dash, dealing damage to enemies he passes through. Cant go through terrain.

W- Charges his next auto attack, either slowing enemies hit by his auto attack cone, or stunning first enemy hit if his aa is a line. Auto attack reset

E- Not sure.

R(ultimate)- Generates a storm around him, giving him increased aa speed and increasing aa range by 150. So his passive cone would be 1-275, line 276-550.

I know its quick and dirty, but i think ill try to build this up some more. Any quick thoughts?
