I did I brought it down to 1 actually andI still had rediculously high ratings for my arrows and bows. I'm not sure what was wrong with it honestly.
What kind or ratings?
having used many of Dukes mods I've seen extremely high damage ratings and those are by design As Duke pointed out not all that connects when you hit plus the damage rating is generally wrong - get the display stats mods for more accurate readings.
I've seen bows that do 240 and arrows that do 70 - yes. Even so in a high level FCOM game that kind of bow and arrow does not put down an equally matched opponent in one or two shots.
But think about the settings too - if the you set archery to 3x then if I understand that correctly then this will be multiplied after any other modifiers, so if a mod already doubles the damage then it will get multiplied as well.
Read the Nexus page on Kuertee Attribute and skill damage mod - he breaks that down in a lot of detail.
