I've recently experienced something kinda annoying: I queue for a dungeon, and then I get an offer for joining a run in progress. That sounds well and good, but when I zone in, I discover that I'm all alone. Is this a bug?
Either way; would it be too much to ask that the last person to leave an instance closes it, rather than leavingit open?
Also: If you all agree to leave, then don't say yes to finding replacements for the players that left.
