Seriously.. fix this.
We killed the last boss of Amdapor Keep and someone left and the leader filled the slot...someone else left and the leader DID IT AGAIN. Got a healer an dps in <15 seconds.. Pretty atrocious thing to do, but worst to allow it to happen in the first place.
If last boss has no lifey, find members button should no worky (as well as taking a group out of the queue if they get the kill while in the queue).
