Where exactly are you doing ur parsac? Any force attack is above 100% or at it when it comes to accuracy. Pve and PvP are different when parse. In the middle tree their is a skill that you gain 3% accuracy so that should be enough.
Now, their are a lot of aurguments when it comes to power or strength augs. I did an experiment where I crafted a each strength and overkill mods for my PvP set. The results are somewhat like this. With all strength augs u gain an extra 1% to crit but lose ~10 bonus DMG. With overkill you gain 10 overkill but lose ~1% crit. If you are going rage/focus you want power because 1) we don't get a skill in our trees that increase our main stat. 2) you gain an auto crit with rage/focus.
If you like I can post my PvP build and when I get home, I can record a couple matches and u can determine if you like it or not.
