I remember back in ARR I was in some primal extreme farm, and someone always kept holding up the loot. Then someone in the party said everyone type what you rolled. Things changed rather quickly. I have asked this a few times since and that has worked.

I honestly wouldn't mind if they found a way to start outing the people in alliance raids with a highlight color or something that they haven't rolled. I have no problem waiting out the clock either way, in-case there is a griefer reading this.
