An acrobat support concept kit

So had an idea for a slippery healer whose an engage support.

Passive - every third auto on champs he procs an effect like static shiv, but he heals alies instead of dealing damage. He also gains 20% movement speed when he procs his passive for 1.5sec. And the amount of jumps scales with lvl. And can jump to the same champs if there are no unique champs around. 3-6 jumps. Gets one with every ult lvl, so 6/11/16. Hes melee

Q - deals damage infront of him and slows enemies. Mid range, imagine senna q but low range

W - gains range where his staff is longer (his range goes to like 400 range) for his next 3 attacks and 100% attack speed. And his autos put a slow on enemies hit for like 20% movement slow for 1 sec. It doubles if the same target is hit.

E - small dash where he's cc immune but not damage immune. Very fast and short dash

R - his ult is him transforming his staff into 400 range for 5/6/8 sec, gains 50% attack speed and 50% movement speed. And his e gets a 2 sec cool down. His passive gets an effect while in ult where it procs also on enemies and slows them by 5% and it stacks up to 70%, also his passive heals give movement speed per stack 3% up to 21% movement speed
