The way I use Foresight: I made a crappy defensive combo with useless skills:
#1: Foresight - Bloodbath - Featherfoot - Awareness
#2: Foresight - Bloodbath - Featherfoot - Mantra

This way, I always have one of these useless buffs on (because, let's face it, none of these will save my life).
I consider it reduces on average my damage taken by 3%... something like that xD

Panic buttons are: Vengeance, Thrill of Batte and Convalescence
