Joining a Party in ProgressFollow

Just curious if anyone else does this on a regular basis when dungeon crawling. Does it only ever send you to a party already in progress? I've done so about 5 times today, and it's always just that. Not to mention you'll run into some interesting stories about why x class you are replacing is no longer there. I like it's an option, rather than a straight up just place you in a party upon first come.

It usually guarantees you catch a failed run where one guy is afk after everyone else left to avoid the 15min lock out from leaving

It would make sense if DF gave preference to placing you into a party that was already in the dungeon over a group that was in the process of forming. After all, DF can only fill those holes in parties already in dungeons with people who have that option set when searching.

Your experience is probably an indication that there are more parties in dungeons that need to replace a member than there are people willing to join a dungeon run in progress. If there were more people with that option set than there was a need for, then you would start to see cases where you get placed into a group that is preparing to enter the dungeon.
