alright, while everyone is discussing their favorite Broken Steel Trio, let's discuss something slightly different.
Regulators - Buff them. So you have some Duster clad boy scouts who think the best way to combat evil is to approach it directly while wearing no armor. Sure, their guns are nice...ish. Eventually they may even be able to break through my powered armor, but with no armor on them and a few swings from my Rebar Club, these poor saps don't stand a chance.
Raiders - Ok so here we have an interesting case. Low armored people who are consistently hostile to the player, or to ghouls, or to pretty much anything in existence. They lack the firepower to match the Fiends, they are a low level hazard, but at the level that I am at, they are worthless. I'm not proposing that you buff them early on, because that is not the case. They have .357 revolvers that can punch through armor nicely. But that is their only trick. What if we added a wider variety of weapons to their arsenal to give at least some more diversity to their numbers, but also consider bringing some of the Pitt armors to them? At the higher levels, 20-30, i'd expect the raiders to be using Laser rifles, hunting rifles, combat shotguns, .44 revolvers, with rare trail carbines, hunting revolvers, incinerators, and grenade launchers.
Yao Guai - Buff. These guys have no Damage Threshold or resistance to speak of. I wiped out 2 with a service rifle and standard 5.56. maybe 3 magazines of ammo were used. these guys are free 50 XP and only pose a danger early on.
Slavers at Paradise Falls - Buff. I know this is an odd one, but when the highest weapon these poor saps have is a minigun that one person uses, and they all have armor with little to no DT except for Forty, you'd think there might be some questions as to why the slaves don't just revolt. I think this may be one of the buff for the later half of the game where they get combat armor and higher tiers of assault weapons, including marksman carbines, trail carbines, and maybe even the two metal armor boys Ymir and Jotun getting some Thermic Lances. Bottom line is I think two of them can actually have a gun that can punch through my armor. and they don't have really any armor.
