As someone on Sav A1, I'd like to add that Foresight lowers the dmg of Prey on me from around 3.4k to about 2.3k a hit (it hits 6 times). I've tried keen flurry also, and noticed that it never parried once, even with 40%. It's possible the move is not affected by parry. I've yet to put much use to bloodbath (how much does it heal usually for you guys?)
