Flash - The Lightnings Fury

Hello Summoners, I am Lisarah a League of Legends fan boy and I believe I have a great mind for Champion Concepts. This is the perfect place to share my ideas and obtain feedback on my creations. There will be no art here; since; well; I draw like a 3rd grader but other than that ladies and gentleman please enjoy.

Champion: Flash - The Lightnings Fury

Role: Marksman

Passive: Flash gains Lightning as a resource, It generates passively (+1/sec) and every auto attack gains 2 lightning. Flash gains Increase range (0.5) for ever point of lightning he posses. (Max Lightning 100)

Q: Flash consumes all his Lightning then shoots a burst of electrical energy in a line dealing increased damage and range the more Lightning he has (1.0 AD) (12 sec cd lvl 1).

W: Passive: Flash's auto attacks have a (25%) chance to jump to another Champion dealing half damage. Active: Flash stops gaining Lightning and get increase attack speed (30%) for 7 seconds and all his auto attacks jump to an enemy champion dealing 40% damage. (20 sec cd lvl 1)

E: Flash turns into a bolt of lightning and dashes a small distance (cost 5 lightning). (15 sec cd lvl 1)

R: Flash enters a Lightning frenzy gaining 100 Lightning and none of his abilities cost lightning for 8 seconds, If hit again within (1 second) Flash consumes all his Lightning firing a massive bolt of lightning. After hitting a Champion dealing (300 physical damage + 1.0 AD)the Bolt explodes into an AOE dealing (100 magic damage) and applying a 30% slow to near by enemy champions for 2 seconds.

Summoners if you have gotten to the end of this post please post suggestions and voice your opinion on the concept. I believe this Champion would have a great skill cap being able to do great AOE in team fight and must manage his Lightning in lane as well as team fights to deal the maximum amount of damage. (P.S. the 1v2 is strong in this one :D)
