He has pathetic armor and and his head is completely vulnerable. A weapon that fires as many high velocity bullets as quickly as it does should kill him before he, with his fist thing, could kill me, the supposed tank. Or, in the case of Lanius, my military grade weapon should kill him before his car bumper on a stick kills me, the supposed tank.
I just looked up Praetorian Armor: It has a max DT of 12... and you are shooting him with a minigun that can only do 12 damage per shot- case closed. Just because you have a very big gun doesn't mean it's going to do very big damage all the time. Go get some armor-piercing ammo.
If they were wearing power armor and wielding Anti Materiel Rifles, no, I wouldn't complain as much, assuming the experience was exactly the same, other than that. As it is, the half-naked fleshy things should be turned into swiss cheese, not be killing me with 4 hits while I struggle to kill them.
At this point, I think your complaint has more to do with what the game art is presenting to you as opposed to how the developers balanced out the underlying rule mechanics. Maybe they should have stuck the Legion's elite in tribal power armor and made their ballistic fists steam-powerd glowy death machines to satisfy you. In the end, though, I now realize that you are complaining about the final boss battle which is SUPPOSED to be hard because... it's the final boss battle.
It's a little bit of both. Small weapons shouldn't harm me at all, in my opinion,
In that case I think you're freaking out just because the screen blurs and shakes a bit when you get hit with a low-caliber gun. This makes sense to me because while you may be wearing a metal suit, you are still vulnerable to some concussions inside that suit.
but when facing multiple enemies wielding guns, my hit points are dropping at a rapid pace. I used up all of my 27 stimpacks going from the Hoover Dam to Legate's camp and the guy with the bumper as well as the guys with the ballistic fists are killing me far too easily while I'm struggling to do the same with this oversized, military-grade weapon.
NOW it becomes all too clear to me: You're talking about the final battle! Jebus Christmas, guy, it's SUPPOSED to be hard because it's the FINAL BATTLE! Some of those Legionaries are shooting at you with Anti-Material Rifles and charging at you with Thermic Lances. Now I realize they also use smaller caliber weaponry like Assault Carbines, but they could be loaded out with AP ammo for all we know. The Legate is a VERY BIG DUDE who has killed hundreds of people by himself, so it should be no surprise he can tear you appart with his sword. For all we know, he MADE his sword out of the same metal as power armor or found something even harder to work with.
As a test, when I first got power armor training, I took my fully repaired suit and tried as hard as I could too clear the Strip. 3-5 NCR soldiers with clubs at once posed a very real threat to me.
I'm using Brotherhood T-51b power armor.
Now this is genuinely befuddling. A fully repaired suit of T-51b has 25 DT. Are you wearing a helmet at all? Maybe New Vegas will not let your DT protect you at all if you get hit in the head while not wearing a helmet.
What's your Endurance, by the way?
EDIT: After some quick research, I discovered that the MP's on the strip are wielding Cattle Prods. Cattle Prods do "fatigue damage" which means it might be outright ignoring your armor DT altogether. Kinda makes sense to me since cattle prods do their damage by shocking you, not necessarily bludgeoning you to death, and metal conducts electricity last time I checked.
