Utility ADC Concept

Here is my medic ADC idea. The idea was derived from a person who made a concept of a heal on auto attack support.

Passive: Every fifth auto attack will apply a heal to a targeted ally (including self).

Q: [Active] Gains bonus attack speed, attacks steal a percentage of the target's health, stolen health is stored. W: [Active] Target's an allied champion, runs to that champion (ignores unit collision) while gaining a massive amount of movement speed. Once the champion reaches the allied champion both gain a shield and are healed with stored stolen health. E: [Active] Dashes in a targeted direction and attacks twice on the next basic attack. R: [Active] Modifies all abilities; Q - increased health stolen and attack speed W - teleports and shield is stronger E - Can dash multiple times (3 charges)
