Servos are relative. I’m currently using 15$ servos to make an Arduino robot wander around a room. It’s just a motor with fine control systems, not military grade magic. Even if the servos could perfectly counter every bit of weight of the armor, the thickness of the armor would still restrict your movement. The more you armor the joints, the more restrictive the armor is. It’s not the weight of the armor, it’s the fact that your joints get smaller the more armor is around them.
It isn’t sealed, so it doesn’t have air intakes, so it can’t have air filters. It can’t have air filters anymore than a hockey mask can.
Yes, but if the electricity hits a metal joint and the only path it has to the ground is your body, it will go through your body. Think about it.
Regardless of how electricity actually works, it’s handled oddly ingame. This bit is just balance, so don’t worry about it.
ALL power armor ingame seems to be a prototype to some degree. Otherwise it would show up far more often in military installations. Just because the project cost millions doesn’t mean the product itself did, and completely sealing a moving object is far more difficult than you seem to think.
It basically is though, that’s why it’s basic. Some armor plating on an exoskeleton, that’s power armor at its most basic. That’s why it’s basic power armor.
