Frustration with not being able to add to party in a dungeon.

[Maelwys]

(how many people actually check the "Join a Party in Progress" option?)

*Waves*

All. The. Time.
To the point at which I wish they would implement an "only join parties in progress" option so that I didn't have to occasionally withdraw from 'new' groups whenever I'm in the mood to replace somebody.

It cuts a lot of time off Myth Tome farming to join a group that are 2/3 of the way through the dungeon
Seriously, the amount of AK groups I find that are stuck on the Demon Wall...
