Important bits have been said at this point. If you don't think Glaroilficosis and the DoTs are filler, it's clear we've been talking semantics in circle. I'll stop pushing for clarification and agree to disagree then move on.

Also not gonna lie. If the effect of Seraphism didn't turn their GCD healing into instant casts, maybe that oughta be fairer. At the very least they would still retain SCH's weakness that is raw heal output on the move.
