Projectile Heals
What if a champion had a healing spell that was a projectile, like Ezreal Q, except it heals allies instead of doing damage. Additionally, it could be blocked by enemies (they wouldn't be healed, they'd just stop the projectile) as a form of counterplay.
is the closest thing we have to a skillshot heal, but its AoE not a projectile.
Heals are usually tough to balance so I don't see this as a terribly viable option. It'd still be cool try tho.
