Constant interrupts or Skills that specifically interrupt?

Wait, I thought scholars couldn't inflict heavy in pvp? White mages can.

Every othery second you get a Ruin thrown at you. WHM can only use Aero and that does roughly 1/3 the dmg without Clerics.

Can't mount or anything just equidistant consecutive 200+ dmg that's instant and doesn't stop.
