I'm getting destroyed in multiplayer and I'm trying to decide whether or not I should buy some of the cheap 5000 credit packs just so I can hopefully get some new weapons, or if I should save up for one of the rare packs and hope I get something awesome.

However, I have no sense of what kinds of things to expect in the more expensive packs.

• What types of rare and uncommon items exist?

• Is there a list somewhere that says which items you can get in the rare and uncommon packs, similar to how a game like Magic: The Gathering has a master list of all the cards in a set?

I need to know what's possible so I can make a better informed decision about how to spend the few credits that I actually manage to scrape together.
