For those who are unaware, Precision no longer halves your damage, and instead of +4 ab, now gives +5% chance to hit and -25% fortification to your target. No, I know that second part isn't listed on the feat. It's on the wiki though, and it works. I was critting a combat dummy with no debuffs.
Precision is so much better than Power Attack now that I cannot see any reason to ever activate it, since the two stances are mutually exclusive. Precision also comes at the cost of a feat, and the only one I could stand to part with for it was the Monk Past Life. I could drop Power Attack and Imp Sunder, pick up the Monk Past Life and have an extra feat to spare, but I think I'd really miss that stacking fort debuff. Thoughts anyone?
