I've had an idea of improving heal, dunno if it's good though.

Heal is currently overshadowed by Barrier because barrier blocks more damage in a clutch situation than heal does.

What if Heal wasn't an instant heal, but a big increase of your health regen over a couple seconds and make it heal more than it does now. That way it can get countered with ignite or grievous wounds in a fight, but it becomes better when you use it under your turret because you really can't afford to go back right now.
