Precision vs. Power Attack

[karl_k0ch]

With the u14 change of Precision (granting +5% to-hit and 25% fortification bypass) and the whole combat system, a challenger of the Offensive Stance slot previously taken by the Power Attack feat did appear. I cannot provide detailed math to prove why one is better than the other (I have no agenda I'm trying to push here), but I'd like to have a discussion with fellow rogue players on their views on these two feats.

According to probably outdated info on the wiki, grazing hits apply only the base damage of the weapon and sneak attack damage (no Str bonus, nor PA bonus, nor weapon bonus, nor additional effects). According to a dev post, players graze on a 2+, i.e. you will not see actual misses against mobs, but having less to-hit will reduce your total damage. But even on a grazing hit a lot of damage is actually delivered via SA damage, if applicable.

Precision

• Can increase damage via critical hits and sneak attack damage if the fortification isn't reduced to 0% via other means (Opportunist 10%, Improved Sunder 10%, Destruction 4%, Improved Destruction 8%, Grim Precision 5%-15%, Armor-Piercing 10%, Insult 20%, Piercing Clarity 5% - 10%, Shield of Condemnation 10% - 50%; not all bonuses might apply at the same time)
• Can increase damage by raising the hit chance by 5%, essentially converting a grazing hit into a regular attack, if your AB isn't already greater than 1.4*AC - 10.5, where AC is the Armor Class of the Mob attacked.
• Can increase damage by lowering the fortification and thus allowing to apply the Sneak Attack to-hit bonus more often. Yes, a mobs fortification penalizes your SA to-hit.

Power Attack

• Will increase your damage on proper hits (i.e. no grazing hits)
• Can increase the chance of grazing hits, unless your AB is greater than 1.4*AC - 5.5

Thoughts?
