Assize should have second charge

That's exactly why their burst window is weak because consistent damage is good.

during the burst, Sage can only use that extra skill 1 - 2 times and that is 180 - 360 extra potency during burst window relatively Nonburst window

WHM have POM + Assize + potentially misery

AST have cards + Divination + earthly star

SCH has Chain Stratagem + Energy drains + Dissipation

If all healers have somewhat the same balanced DPS, realistically thinking Sage should have the weakest burst window.
