My Champion Idea : Ventus
I had this cool idea for a new champ, Ventus (Latin for wind) He would be a fighter / marksman and would have a body type / form similar to 
passive: Raging Storm: (This would replace mana for a fury like substance) When he hits his enemies with his basic attack or one of his abilities, the clouds around his body start to turn darker and admit static from them. When the gauge is full he can choose one of his abilities to use in his storm mode (maybe his passive could scale with critical strike items or cooldown reduction items, most likely cooldown)
basic attack: Ventus is seen slamming down both of his arms on an enemy and you would see a rush of air push the enemy down
Q: Gust: Select a route to use the ability (medium length line) Ventus summons a strong wind to rush in a certain direction damaging the target
Q: (full gauge) Gale: Ventus summons a sudden strong dark wind into a certain direction, with more damage and knockback
W: Mistral: Ventus summons down a (medium) circle of wind that slows down any enemy champ to cross it and gives off slight damage (similar to Miss Fortune's Make It Rain)
W: (full gauge) Funnel: Ventus summons down a (large) circle of wind that slows down anything to cross it and gives off slight damage (little bit more), and if any enemy champion stays in there too long they get stunned
E: Crosswind: Ventus summons a wind that gives him a speed boost and carries him a medium distance (medium length line)
E: (full gauge) Split Breeze: Ventus summons down a wind that gives him a slight speed boost and carries him in a medium distance, and when used knocks back any enemy champ behind you
R: Whirlwind: Ventus summons down a funnel of wind (about as big as Zigg's ult) at a target location (radius of about Zigg's ult) that does high damage
R: (full gauge) Eye of The Hurricane: Ventus surrounds himself and anyone else near in a hurricane, that slowly sucks them towards Ventus and has major damage (radius of Gangplank's ult)
death: Ventus is killed and his remnants fly up into the sky, so fast creating a sonic boom, pushing nearby enemy champs away
well, i hope you guys liked my idea, it took A LOT of thinking. If you guys like my champ idea and think it should become a thing, comment and like so Rito can see and make this happen, also comment with your own champion ideas.
IF MY CHAMP IDEA GETS ENOUGH ATTENTION I WILL ATTEMPT TO DRAW AND POST MY VERSION OF VENTUS
