A New Darkin Champ concept.

Mind you guys, this is a rough draft, but I want to see what the community thinks of my idea for a Darkin hybrid Drain tank melee battle mage.

Passive: Gains increasing life steal from all damage dealt, based on level.

Q: Is a toggle, always on with 2 modes to switch from: First toggle grants AD and AS, second toggle takes away those steriods but grants Auto Attack range.

W: Deals DoT in a circular AoE around him, applying a slow. Can be deactivated early to steal hp from enemies within AoE, reduced damage to minions.

E: Sheilds self for %max hp, deals a tiny burst of AoE when finished based off of how much damage absorbed.

R: After a 1.5 second channel, deal AoE DoT damage with each tick draining and stealing life from everyone effected. Can be recast a second time to pull in the DoT into a ball, and shoot forward a beam of black flames based off of %missing hp of enemy hit

This is just a super rough draft, I want to work on this and push Riot to make a champ like this. I straight up would pay to have a champion like this
