Today was in a DF party where the DDs didn't focus on an add. They were told to focus on an Add and we prepared to try again. Then the WHM left before we could.

Maybe he ran out of time? More than likely he gave up on the party after one try. I guess he was WHM so he could cue up again quickly, but still. I feel it's poor form that act like you never wipe and therefore no one else should either.
