15% increase ad probe and all AoE, I dont even use sniper fire much anymore i spam surpressivepressive which base damage is 2000+ over 3 secs 15% is a extra 300 damage with high crit I recommend at least 33+ crit and since the surge nerf i keep mine at 72% as for cunning and power. The program I made calculated a .44 variance between damage output stacking cunning is a damage decrease of 44% per point if you want bug hits big crits just stack crit/power/surge the crit will make up for the loss of cunning get the 20% decrease armor reduction for ambush and also use shatter shot for an additional 20% I'm orbital strike spec as well and am picking up field tech BM so 40% reduction to armor and having 107% accuracy with special attacks ive been able to hit 3-4000 over a 3 sec channel of supressive fire and my OS has topped 4k... OS flashbang surpress fire corr dart works wonders
