If I click " join party in progress " is that an absolute that it will ?

Confirming the above. I used that option some times, but as DPS I will end up in dungeong that already screwed up and people leaving. Maybe good for tank or healers, but as dps I stopped clicking on it.

Yah you can still get fresh dungeon but as others mentioned usually it ends up being a party on verge of breaking, I stopped clicking it as DPS, but as healer isn't a problem
