I think the proper fix would be a fourth category in the looting options. The greed option was intended to take care of this exact problem but i don't think they intended it to be used to force any particular player to receive loot, as we tend to use it currently. I am sure the post it to the forums was to let development know the user base is interested in this and possibly farm for solutions. Best bet would be to go with:
Need - current function
Greed - current function
Defer - tier under greed but with same function
Pass - current function
