How it uses lazer rifle? Huh? If your shooting eyes, it has shit range, if your not a critical build it's self explanatory that it's a crap build only for killing some bluesuits. 1 Str + weapon handling + lazer rifle is -60% to EW skill, lol, what are your running 10-15 hexes close to hit someone?
I have a sneaker with 1 str + weapon handling and using lazer rifle on aimed shots is totally crap, pistol surpasses in range due to lower requirements + one hander when it comes to shooting arms/eyes, aimed shots.
Gatling is different story it uses normal shots and has long range witch is a major boost for accuracy for uncalled shots, but it's -72 for sneak, good for killing some static scouts during town control, i know how avv "uses it and says it's doable", even better if you minimax your sneaker with 270 sneak and ghost and gatling, it's going to be 198% sneak on open field and other sneakers will basically smell you from 30 hexes.
