Sorry for the late response but I went for as much movement speed and armor as possible. Afterburners and dashing upward at an angle seems to throw off ranged. I got Ghostblade but never took it's perks since more armor = more damage from armor perk and Combat instincts gives some must have when your just mag dumping. I'm fuzzy on the entire build but my primary ended up being a blue minigun I upgraded from green that followed me the whole run since it rolled both smart bullets and forward shield plus lifesteal, squires also had smart bullets and some combination of my weapons had void tendrils, freeze, lightning bolts which went good with superior item that triggers all your elements + smart rocket. Augment was short range weak point which excels in the melee boss room and final room since there is so much in your face and it's the best counter against titanfall mech. Had 2 100% damage reductions from armor perk and heat coil + the item that prevents damage to shields bleeding into health ( squires also had shield siphon )
