Character Slots/Account-Based FC

So given how we have absolutely no reason to have more than 200 FC given that is how much we need to max our character from the very beginning(Max cost). It is time we should obtain a save slot system and make FC account based(Aka key.) so that we have access to it on each of our save slots there by giving us something to spend it on after 200 FC has been obtained. Hell even make it to where we can buy slot in the FC shop I don't care.
