I like gold on floor, though I'd prefer if it was split while in group. Likewise if the skins/material drops could rotate around the group, so it doesn't matter who picks up it goes to the next person in line. It's not a question of trust, it's a matter of trying to make sure everyone gets their fair share of drops. You could do the whole one person picks up all and sells at end, but then it's a question of do they npc the materials of sell on TM, then how long it takes to sell etc.
