Something I'm noticing a little more is the use of greed to swipe up loots that really ought to belong to the original killer of the mobs. While I haven't lost anything valuable to people using their Amistr Greed Bags, I could see the potential. I vaguely recall the GM team saying the looting time is fixed, but it might be worth revisiting to avoid some unnecessary drama. The period of locking out other players from taking your loot is just a little too short.
It might be worth revisiting.
