(1)Main spec before Off spec
Write your Main Spec in Guild note.
Once you decide your main spec, you cant change your main spec in 2 Weeks unless guild needs.
(2)You can not roll for what you need for 2 Times in a row.
If you won item first time, you can not roll 2nd time.
You can roll if noone wants that.
(3)Pass it for someone who doesnt win anything.
If you get 2 or more items through the run,
Pass the item for someone who doenst win anything.
So everyone get more chance to win something per a run.
