champion concept: rekon- the defected engineer

I have a champion concept that might be interesting. Rekon (pronounced recon) is a Noxian military defector who was injured during a battle with the Demacians. He defected the military after witnessing the horror of the battle. He went to Zaun to get assistance to create his prosthetic arm (which is more of a weapon than an arm). His new arm is an energy rifle with an under-slung grenade launcher. He later joins the Demacian military as a scout. Passive: capacitor Every ability and auto-attack gives a capacitor stack. At 5 stacks, the next ability/auto attack deals bonus damage (scales off of bonus mana)

Q: peacemaker Fires an arc of energy that slows for 20/30/40/50/60 percent for 2 seconds (deals AD, scales off of AD, and small amount of AP) W:Target tracker Fires a projectile that, when it hits an enemy champion, grants true vision for 2/2.5/3/3.5/4 seconds (deals magic damage, scales off of AP) E: Proxy mine Plants a mine that, when an enemy champion comes within 150 units of the mine, will bounce up and fire a pulse of energy in a 400/450/500/550/600 unit radius. Damage is also scaled by ability level (deals AD, scales off of AD) R: Flashbang Fires a grenade out to 1000/1150/1300 units that explodes, and confuses the enemy (a new confuse mechanic would be added. This mechanic would invert the player's movement commands, as well as slow them for 40 percent; for example, clicking to move the champ forward would move them backwards, and going to the left would go to the right) (ability scales off of AD and AP, and deals magic damage).

This is an engineer-esque ADC champion that is more weighed in on CC than mobility and raw AD. This ADC will be able to peel for themselves if they are caught out without a support, something that some ADCs cant do very well. I have yet to make a visual representation for this champ, but feedback would be well-appreciated :) TY
