Nasty hexo build for last stand and skirmish. Good in DZ too. I've been ripping down predator and striker builds with this. Skulls gloves are bread and butter. Barretts chest could be swapped out for vigorous if you'd like. I'm not keen on reckless with this build as you'll be right up in the fight so the increase in damage to you with reckless just seems like it isn't worth it. I chose two classified pieces to add, the backpack and holster so as to reep the max stats when optimized. Make sure they aren't a match or the skulls gloves won't work. I rolled a lot of health an edr on the gear to make it as tanky as possible. Plus with smgs and the right weapon mods, you'll have plenty of chc/chd. I did test it with all chc gear mods and all health mods, both are good. I just personally tried to balance it a little. You could use immunized if you like. I like the booster shot...when it's couple with the effect of the tenacious mask, this build becomes really nasty. One other thing you can try is stability on the backpack with an AR as a secondary. It really made me shoot like lasers. Might switch back to that honestly. I choose the pp-19 simply because it puts out some solid damage and with the extended mag can shoot 100 rounds.
