I combo foresight with vengence sometimes and if used with path and IB active it's like nothing hurts at all. But I use it on trash mobs or if it's too late to dodge AOE I use it to mitigate some damage. It's better then being bare naked. I combo it with rampart or shadow skin. The higher your defense the stronger it is. Not saying much since others lowers damage reduction. But with better armor it should scale better.
