An ADC-based Support (Champion Concept)

So i've been thinking: there are all sorts of champs that get used in the support role (and not just for troll purposes.) made his way down bot most recently, but champs like and also work as support when played correctly. There are all sorts of champs that can fill the role of support even though they weren't intended to do so originally. So why isn't there an ADC-Support mesh? (Other than the occasional or ) My idea is an ADC style-based champion that has been meant for the supporting role since the beginning. When i think of support there are a few things that come to mind: 1.) can they heal/buff their allies? 2.) Do they offer any form of CC? 3.) Will they make enough gold to have an item-impact in the game? And i believe i thought of a pretty creative way to handle all of those, while at the same time having clear downsides and a kit that can be easily tuned so it's not oppressive or OP.

Passive- Healing your allies through auto-attacking them. It will heal for a small portion of missing health and your own AD (further stressing the ADC-Support style of play.) The auto attack speed will be GREATLY reduced to prevent spam-healing for free, but will get slightly faster as the game proceeds. (I understand there is an Overwatch champion that does this, but i have no way to prove that i thought of this before her release)

Q- A stacking ability, like or . But it will only be temporary. Auto-attacking will give you a buff that increases your AD for each stack, maxing at 5 or 6. Your AD will be reset whenever its timer runs out. (Again with the ADC style. My first thought was people just taking this champ into ADC itself, but the rest of the kit will prove that to be a very poor and fruitless idea.)

W- You sacrifice a part of your own AD to an ally. (This is why ADC would be a poor choice, this mechanic and the mechanic on the E ability really puts you at a disadvantage compared to other ADC's like or ) During this time, if you AND the ally attack the same target, they will be stunned for 1.5 seconds. The buff lasts for 4 or 5 seconds. (A target can only be stunned once per activation to prevent any sort of cheese double-attackspeed builds.)

E- This ability is basically a . You target a specific enemy unit and if you land the killing blow on that target, you and the nearest ally will get full gold value for the kill. I imagine this ability working like and , where everytime you use it in succession, it will cost a little bit more. So you will have to decide how often it is worth the mana cost to use. (This, in combination with another gold-income item, will give plenty of gold to make the champion useful, and since it has no effect on enemies whatsoever it will be a fairly pointless ability late game once everyone has their builds complete. And it's another prime reason NOT to take this person into the ADC role. As an ADC the minions are already yours for the farming, sharing with your support would just be a thoughtful thing to do, if not a waste of mana.)

R- I haven't thought of anything EXACTLY to be the ultimate. I've thought of a ult and Q- combo where you have a certain amount of shots that do an okay amount of damage, but will hurt everybody it travels through. Or i've even toyed with shots that have different effects depending on the HP of the target (stronger healing for low health allies, or DOT effects for healthier enemies). It's got plenty of potential.

Overall i think it's a really interesting combination of role-mechanics. And it would definitely be an interesting build-path: is something that comes to mind. Of course, I'm just spit-balling and wanting to see what you guys think, how would my magnificent creation fare on the fields of justice???
