Ok, i might be wrong here. Or actuallly i'm sure i am. Anyways, I'm under hte impression that you can't use mag cells on your mag until they turn level 200. I'm also under the impression that feeding a magcell to your mag won't let it go above lev 200. That they don't get any new PBs either even if you have a spare slot.

Now assuming i'm right, what exactly is the point of giving them a magcell? Is it just for appearance or what?
