For the weapons: - we can add the SP only weapons such as chakram launcher, particle rifle, AT-12 Raider, M-55 Argus. I know that they are promotial content but it can be intersting to use them as ultra rare weapons or unlockable items if alreayd unlocked in SP (and possibility to upgrade them if found in packs: same idea for collector rifle who is only lvl 1) - I think it is already said but we should add the SP heavy weapons to MP.
