There’s not enough Vending machines. They are pretty much just at the start of each area. By the time I get to the boss room, my inventories full. I then have to drop several things in order to pick up things from the boss fight. There should be vending machines outside of the boss rooms. Otherwise if I want to vendor before fighting, I have to either run back to the very start of the map (or fast travel), and then run back through all of the respawns. Of which by the time I do this, my inventory is full again… Previous games have had a few Vending Machines spread through out the level, you didn’t have to be so selective in the items you pick up as you do in this one. At minimum a Health and Ammo vendor should be present before the boss.
