Wind ADC champion with self peel
Dashing champion.
A wind adc who uses a finger pistol which shoots out highly compressed wind from the tip of his fingers.
Passive: Pressurised Air Holding off from attacking while an ability is up for 5 seconds increases that same abilities damage. Same applies for basic attacks.
Passive 2: Breeze Moving grants up to 4 bars worth of energy which all abilities require. Movement speed from items are converted into attack speed.
Q: Wind Slinger (1 energy) Cooldown: 12 - 8 s Unleash a barrage of 3 wind bullets at a targeted direction which can be redirected through dashes. Cooldown reduces for each wind bullet that hits an enemy champion or kills a minion.
W: Blast Gale (1 energy) Cooldown: 10 - 6 s Summons a gust of slashing wind at a target direction. For each second charged up to 3 seconds, it increases in range, width and damage. Activate early to release. Works like Jannas tornado.
E: Trail of Air (2 energy) -> (1 energy, at level 5) Cooldown: none Passive: Grant +5/10/15/20/25 movement speed Dash in any direction.
R: Surging Gale Force Channels for 0.5 seconds and unleashes a blast of wind at a target direction for 3 seconds slowing enemy movement speed towards the point of surge while dealing magic damage every half second.
Thoughts
could just constantly harass you with no consequences). This would mean the champ would only need to base to purchase items or to regain health. Second is that most adcs only have one escape ability (some have two but they require you to jump through a hoop or two to make them stick ala 
E) but this guy has three peel abilities which makes the guy almost nigh uncatchable unless you hard counter him with something like 
for example. The big offender however is his E which is basically just better 
E as unlike lucian's which has a rather lengthy cooldown (22-14 seconds) this one has no cooldown and gets the resource back just from continuing to walk away (he'd be a nightmare to gank and frustratingly elusive to lane against). Like I said at the start it's a neat concept, but I believe it runs into the 
problem, he sounds really fun to play but incredibly unfun to play against. But keep working on it, with a few tweaks he might make a neat solo laner or maybe even a jungler!
