Heal shouldn't Do what it DOES
We've seen heal go up and down in it's popularity, with the nerfs, the buffs, the addition of Barrier. Normally I didn't find it an issue, it adds something to the game, a kind of Clutch moment that Supports can use to save their dying Mates.
But not any more. Heal just doesn't feel right and hasn't felt right since it's last major Change. Being able to Heal two players and give them a massive Speed boost sounds great on paper, but the Skill isn't exactly being used for it's intended purpose, which was a clutch saving move supports could pop out. No, now it's an ADC staple that completely overrides Barrier and Ghost as choices for most players.
Heal needs a Rework. The skill needs to be more tailored to you using it to save someone's ass, not to be versatile for 1v1s or Escapes. Tie it to something, make it Niche but powerful.
I don't understand why it heals you for the same amount of Health as it does your partner, why the same boost is given to you. Tie it to at least 2 Man groups for the full effect, make the Heal more on your target, the Boost as well. Heal shouldn't be a the "Oh shit" button when that's exactly what Barrier is for.
Two Ideas:
(Team) Heal: Target Ally is Healed for X amount, you are Healed for Half that amount. Adjacent allies gain a Stacking MS buff Dependent on the number of Allies in the area. When used on yourself the Heal is Half the amount and Half the Cooldown
This Opens up Heal as a Counter initiator spell late game and keeps it's "Save them" feature Supports are known for
(Rescue) Heal: Target Ally is Healed, you and your ally Gain movement Speed when moving towards Eachother (Range is Large). When used on yourself you are healed for Half the amount and gain half the Boost.
This gives Heal more utility for Supports as a Rescue Spell. Supports can Pick up their allies from hard ganks and still retain some token of selfuse.
Heal can't stay the way it is, it just makes no sense to allow non-supports unbridled access to a supposedly Support spell when they have an equivalent in Barrier.
