I know it's been a while, but can you post this build? I'm interested in playing a sniper/pistol in Dominating.
Gear:
Seeker night vision goggles (smart A-A spearhead with all the crit damage feats is enough to reliably 1-shot almost everything, at that point crit chance becomes more valueable than another smart bonus)
Efficient double low freq shield
Infused pig leather armor with high density foam and black cloth
Utility belt
Infused pig leather tabis
Rapid smart Anatomically-Aware spearhead
Rapid neo luger with a laser sight
Taser and all kinds of grenades
It's kind of an iroman-y build (only reloading on death, goal is to die as few times as possible) I came up with after the infused siphoner tabis nerf, wasn't really meant for dominating in particular but worked really well regardless. I think I died once or twice, can't remember exactly. The overall idea is to have high initiative in case the stealth approach fails or is impossible, high mech DT/DR against melee, shield against guns that also helps against low speed projectiles, high HP for anything else. Also high mobility with a way to break free from immobilization.
Always walk around with the pistol in the hand for bonus initiative, switch to the rifle when needed. Pistol is mostly used to apply Kneecap Shot, reliably hit enemies with high evasion (that's why it's a Neo-Luger and laser sight, also makes it more likely for the Kneecap Shot to hit), delete squishy enemies with low DT/DR up close with Rapid Fire and HP rounds, killing or finishing off other enemies with W2C, etc. Biology is to make focus stims for that sweet 15% crit chance, chemistry is for making W2C rounds.
