This build is obviously designed to work in a group and that's why I spec all but 1 gear piece into FA. I didn't use Pulse skill and mods for it because, IMHO, without SP it still give less damage than Precision with a Booster shot. Theoretically, user can rely on high-SP teammate to provide strong pulse, and then Precision talent can be replaced, for example, with Tactical advance; and Fierce - with, for example, Brutal. And of course Big Al is not a mandatory - I just wanted to show how I see it's usage.It's a subject of discussion about CHD instead of health rolls on KP and BP, but i personally prefer a bit more ability to stand'n'shoot. And personally I'd prefer Fierce or even Brutal on a free slot instead of Vicious - because of it's inconstancy.
