TBH its all about play style, are you using them off CD or on boss fights only?
Im not sure if SH- *Wounding stacks with *Incision, if it does Wounding > Battering > Incision imo. If you're using it on boss' only Id do Aim > Battering > either.
Pelting strikes I myself did Thrust > Focus > Precision and it works wonders.
BS was Aggression (Weapon dmg vs +hit%, dont need the hit% and the wep dmg stacks with BFG) > Flexibility > Retaliation. **Side note, I play by myself usually.
Currently I dont have warding energy yet but the general consensus Ive seen is Field Force > Field Force > either.
Hope it helps you some. As for your other question, I keep mine at w/e my exalted warrior focus says, just be mindful of cooldown times, if you're using them right off CD keep'em low, otherwise you can pile on the BFG and battle stance buffs.
For anyone else looking for any useful dmg tips, I would strongly invest in *+Regen per hit rings with +skills in socketed gear and ring slots. I have +2 sec regen per hit without trying with my pelting strikes@ a 2.6 timer and it pretty much is always spammed, really quite something.
Just my $.02, have fun.
