You might have overlooked IWT looting if your doing a melee team, since obviously looting like that will make you accidentally loot (and perhaps skin/herb a corpse) during combat and if you are spamming too aggressively you can get stuck looting a corpse.

I use a meta key off my IWT key that round robin IWT for looting. It seems work ok and lets me skin and so forth. Also it distributes the loot across the slaves nicely.
