MMO-champion, I'm drowning in information!
Question though; the new roll system for LFR isn't very clear, do we get 3 or 4 rolls and if we win one we get a piece of loot?
From what I understand - everyone gets ONE roll, from the top roll down each person who has a bit of loot on that boss is awarded a bit of loot.
So - if there are 3 bits of loot on the boss, then the top 3 (or more if some of those rollers have no loot on the boss) get the loot.
PS: I imagine you still get to press need on more than one item of course.. if there are multiple items available.
