Even if you are clad in power armor, a herd of Big Horners would still toss you around like a paper plane, only though that you might take it better than you would without the armor. Kinda like the difference of being shot in the chest and being shot in the chest wearing a bulletproof vest. You'd have a few bruises after that fight with oversized goats, maybe even a concussion and difficulty to breathe but you wouldn't have 27 broken legs and internal bleedings like you would have without it.
Man, I can't wait to get tossed around by Big Horners! I hope there are some sports practiced similar to bull fighting in spain and standard american bull riding. Both are two very stupid "sports"

Thats what I mean, with the power armor animals like the big horners and the radscorpions and such would have a very hard time killing you if they even could damage you in power armor but they would become an annoyance as they knock you around. Not to mention if you were say on the edge of a cliff or a far drop and a big horner knock you off it the power armor wont save you from falling.
I mean yea maybe some people wouldnt like it but no one forces people to use it. I have four sets of T51b armor and I dont even wear it, I am either wearing the BOS/Outcast power armor or the chinese stealth suit. I dont wear the T51b because in FO3 it has such a high condition which is nice but even a RPG or laser galtin gun wouldnt really chip away at the condition.
Colonel Martyr, correct and if the power armor is too powerful for your tastes who is forcing you to wear it. They could balance it out by offering more than one version of the T51b power armor that has different DT for those that want a challenge or not.
Yes I know I said the condition was too high on the T51B in FO3 but it doesnt go against my point of having a high DT where you need very powerful or armor piercing rounds to penetrate the power armor. I want the T-51B to be easily damaged by those powerful weapons giving it a drawback as being costly to constantly maintain.
