(assuming my earlier suggestion of turning Art of War into a 3-hit DoT, sorry for the confusion)
Broil III is 280 potency, Ruin II is 200 potency.
At equal potency you'd be better off saving the proc for when you need to move or weave, so it wouldn't change the gameplay that much. Less slidecasting mainly.
