I think the 1.13 "improved" inventory system is amazing. I love the LBE mechanic because you can seriously overload a MERC if you aren't careful. Like a merc with only 50 strength might only be able to hold a rifle, sidearm, and a few magazines. Backpack? Forget it. Rucksack? No way.
I know it's very indepth but that is something I love about that mod.
