@Riot @Vesh an idea for Soraka's rework
Let her heal (only Astral Infusion, not Wish) OVERHEAL (can only be triggered once ever so often, so it's not on demand) and grants ally the buff "Astral Barrier", a small shield that absords attack damage.
I think this is a good alternative since her armor buff is getting removed.
1: Astral Infusion is only a heal with no buff, whereas nearly every other heal is either multi-target heal (Alistar, Taric) or a single target heal+buff. (Hell even Sona heals 2, has Salvation passive AND a shield)!
2: It would only work when it overheals, and the shield is only equal to however much she overheals. It would require thinking and skill, BECAUSE -> SEE BELOW
*You heal the target at full for initiations, they get overhealed and can't trigger Astral Barrier for a while. Kind of wastes Astral Barrier.
*When successfully barrier healing, Soraka would get a debuff on herself so that healing allies will not overheal therefore not grant Astral Barrier, timer reduces with level, sort of like Yasuo's timer.
*You heal ally and they get, say, overhealed by 100 or even 10, it will block 100 or 10 attack damage. I think this way is more balanced because it's not a definite value and it doesn't have a flat value so it would be extremely situational.
