If you eliminate the storage of regeneration points when the armour is not damaged, then you are going to have to make all pieces about 150 to 300 kt stronger to make them worthwhile, as you can usually expect your ships to have at least 5 turns before the range closes, and it's currently not overpowered. Either that, or double or triple the regeneration rate. After all, it has to be at least as useful as shields are to be worthwhile, and the ability to repair after combat if the ship isn't destroyed is useless if the ship will always be destroyed.
