Obviously this isnt a high priority but its nevertheless something that chaps my hide. Call me a “loot hoarder” if you want, fact is I have real problems with leaving tons of blues and purples lying around after I cleared an area. So I make the effort to pick up vendor trash guns for the money and to be able to see something (especially useful in arenas).
Whats irritating is that I “have to” go through my inventory before I access a vendor machine to mark everything I dont want to keep as trash so I can sell it with one click. In order for the one-click feature to make sense (because its supposed to be a time-saver) it should sell everything thats not marked to keep. Otherwise it doesnt save any time as it requires me to mark items beforehand. Its just busy work I have to repeat for every full load of inventory and with the amount of guns dropping on M3 (most of them vendor trash) it does cost a LOT of time in addition to running around and collecting them in the first place.
Or…add another hotkey to looting which allows us to mark items immediately as trash when we pick em up. Kind of like the auto-equip from holding E. This might be the better solution as selling everything which isnt marked favorite can lead to all kinds of frustration and irritation. This would require a conscious decision and action on the players part but wouldnt add to the initial workload (looting).
