The amount of loot you get in PoE only works because of the party stash - and I can't decide whether to love or hate that thing. On one hand, it breaks immersion because, well, things don't just travel along with you magically, not even in a fantasy world; on the other hand, you might also say that it helps immersion, because in a real world, you wouldn't just let valuable stuff lying on the ground, you'd go talk to a merchant or something to pick the stuff up for a cut.
I guess what I'm wishing for are some mechanics that would make looting an actual gameplay element.
