Joining Party in Progress Experience

[Mixcoatl]

I spent half my playtime today joining the first four dungeons as a tank with the Join Party in Progress option ticked. Most of the time I queued instantly, but more than half the time I was thrown into a dungeon with 2 damage dealers who were either AFK or standing around waiting for a healer to join midway. I did stick around and chat with a couple groups, but not once did a healer join.

Did the same thing as a healer and never saw a tank. Just a revolving door of DD joining/dropping party.
