Also SCH has fey union which heals more.
This is why SCH became the current healer meta.
Regen is used to mitigate the auto-attacks. It’s the responsibility of the regen healer to cast it on the MT to mitigate them.

If you’re casting a Regen to mitigate a large amount of damage, you are healing incorrectly. You don’t use Regen after a tank takes a 60,000 buster; you use either an oGCD to top them up or you cast a GCD heal (Cure II/Benefic II).
