I understand all of the different loot systems from nee/greed to master loot, what I want to know is if there is a way to do a random roll. IE /roll. I was in a group that downed a world boss and the Ops Leader had it on Master Looter. We had a hard time doing rolls cuz no one could figure out if there was a /roll in place. Anyone able to shed some light on this?

So we just downed a random world boss and the Ops Leader had it on Master Looter. It comes time to roll and it seems to be there is no /roll. Is there some other system in place that I am unaware of? I know there is the option to send it to a random winner within master looter, but that really doesnt help if there are ppl in the raid that cant use whatever the item in question is. So did we overlook something or is there really no /roll?
