Taking "in progress" to the next level.

"Sees dungeon party with two empty slots near last boss, joins with friend, kicks other two and brings in two more friends."

Not that stuff like that would be frequent, (I would hope, but it wouldn't surprise me.) But it would be detrimental.

This is why I am in favor of the current system. Its blind and mkes doing stuff like the above very difficult. Also, Aurum Vale! Pass!

I think its a great idea in its pure form, but you do have to take the snakes and trolls into account when incorperating something into a game.

Some dungeons and trials are very unpopular and would have an even more difficult time being filled if not for roulette.
But I do think some fine-tuning would be helpful. Many times we have been joined by a tank or healer who signed on to help a friend on a different instance but got placed with us instead, for which I am thankful, but a bit of fine-tuning would be useful
