Like so many other things in BB, that’s a carryover from Borderlands (specifically, BL2/TPS). Played some COOP with a pal running a Krieg with a couple hundred items in his backpack. See, even though you can’t pick up anything over your limit there, it still has to GIVE you any mission rewards/etc. So dude had all the boss drops he wanted, or he had a few throwaways on hand. Want to pick up that max-absorb-rate Sham that just dropped? Equip a crap shield from your inventory, then hold [whatever_button] to swap for the one on the ground in front of you. It was pretty nuts. Re-run the story a few times for the junk mission rewards early on, so you have stuff to swap out for any good drops.
So, BB isn’t so different. It CAN’T stop you from keeping gear that you’ve acquired legitimately, and even more, it can’t stop you from picking up gear as you move through a mission. So you just can’t SEE all of your inventory without clearing up some room. You can still edit your loadouts, though, with the X number of items that you can see in the bank. The BB bank is kinda like a hybrid of the BL2 bank and backpack and Claptrap stash.
Anyhow, yeah, gonna make some room. I’ve already sold a ridiculous amount of legendary gear this weekend; for instance, had Geoff drop me the dreaded DOUBLE Firmware Upgrade 1.51 (weak stats, though, and I already have a max-stats one), and oddly they were IDENTICAL stats. Well, that’s 500 more credits than I had before…
Been getting lucky already with the legendary drops, and with Lootpocalypse almost upon us, I’m about to clear out everything that isn’t either white or orange (I like to keep one or two CHEAP loadouts on hand for when I know I’ll need to use a lot of buildables).
