If your "acc is fine", parse that shit, 90~95% is "fine". If you really are hitting that much, you might want to reconsider your gear choices, add more haste, eat attack foods, get minuets, chaos roll. Generally the buffs you can get from food/songs/rolls for att are HUGE, like WHOAMG I HAZ 800 ATTACK XBOX WTFTRUCKBUICK huge. Gearing to hit properly under those conditions has been shown to be an effective way to kill shit.

Damascus Grip: 5 Dex 10 Acc
Which would you use?
