What is the be Healer?

[Houston009]

T13 did not require a monk, many groups cleared T13 without a monk w/o melding vit.

The job has no heals built in GCD that can reach above 150 healing potency

I assume you are referring to AOE healing in which case succor has a 150 potency heal + 150 shield = 300 potency. If used with the mindset of a sch, it'll be 300 potency. The short cd is for solo/burst healing.
