Posted this in the discussion thread, but it got buried. So i'll make my own post.
What if power armour required training to work effectively? Lets just say the first mission introduces you to the armour, but you don't gain any bonuses from it like more carry weight and stronger melee because you have no formal training with it.
Only once you learn from a reliable source do you gain the awesome powers of, well, power armour.
What do you think?
