BUT I thought I'd take the challenge offered in a thread about NPC Power Armor and try to change them.
So, hopefully this is what this mod accomplishes. It only affects Vanilla - I didn't do it for Broken Steel etc.
I have raised all BoS, Enclave, Outcast NPCs to have power armor that is 70-99% repaired - making them much harder to kill.
I assume, if they are wearing the armor, they have the means to upkeep it and would only set forth in good repair - just like the Player. I don't see it being a problem with retrieving it yourself upon their death, because if you are like me you keep your items at top repair anyways. So now it levels the field a bit, plus makes a low level character have to really think about engaging.
Here it is. Let me know if it is totally broken somehow. I tried to play test it with my level 3 character and sniper shotted an Enclave soldier about 20-30 times before he went down compared to 3-5 previously.
