Support Champion Concept

So I'm a support main and I looked at the recent released champs who are supports and the last support released was Tahm Kench on July of 2015. So it's been a while since a support champion has been release and as Camille is coming out that'll be 8 champions since the last support. I was just thinking of support ideas when this came into m head as a new system as a support. It would work like a Draven's Stacks of Adoration but would hold charges to heal instead of getting gold. Here is the idea: P- When you deal damage to an enemy champion you get one stack. Can save up to  15, 30, 50 stacks.

Q- Shoots a star shaped skill shot and gets stacks per champion hit.

W- Consumes stacks to heal that person to max amount possible or until they are full health.

E- Speeds you and target up for 13% of movement speed.

R- Sacrifices your life for a champion of your choice and gives them half mana/resource and health

Rito could tweak the numbers and decide if they are AD or AP but this concept was fresh in my mind and I decided to share it. [slayer-jinx-wink]
