Imo they should have had 2 types of pack a punching. If you press once square (x in xbox?) it should make the weapon more powerfull, but it will cost more and more points (like x2 each time you level it up). If you double tap square or X you it should stay the same level but change it's attachments (it would cost the same it costed to level it up).
edit.

PHD flopper gives away the meaning of fire everywhere...
i talk to a few beta testers, they said PHD flopper will NEVER be in bo2...
i already know where the next map location is...its an extension... BOWLING ALLEY!!
Beta testers don't know about the game's unreleased DLCs, just for the game or the beta they are testing. So I guess that either they said PHD wasnt going to to be able on the first release or theyhave all DLCs tested, and I highly doubt they have the beta for the 2nd DLC already.
