So it's not a large knock back huh? Ok then. Long cooldowns are typical for supports since their skills are powerful to begin with. However, this skill has more range than dazzle, hits hard regardless of range and aoe stuns with no requirement of aiming. It's also the healing move, so their is no decision making on what skill people want first.

You make a good point with the current mana business, but it also means the skill has low mana cost when low mana, and can be used regardless of mana conditions. Also, by stacking alot of mana and giving this to an ally, they are gaining alot of damage for their auto attack. potentially getting 17.5% of a mana stacker's mana as damage is alot, especially when on a carry.

I only compare with Nasus' spirit fire due to it being a large aoe burning effect with a debuff. I know that it gets bigger over time. It's not a bad skill in team fights, though the range of the aoe is kinda small.
