Roll only if you use the item and it is an upgrade.
If you are wearing better gear, pass on the item.
You may not roll need for alts.
If more than one person needs the item, /random 200 300, highest number winning.
If no one in the group needs the item, all members may greed roll for the item.
Winning one item does not exclude you from rolling on the next item.
What do you think?
