Thanks for bringing this issue to our attention. It’s not a bug, though, and Real ID Party doesn’t change the way this system is intended to function.

We certainly don’t want players skipping queues and getting an unfair advantage over players that are waiting patiently. Ultimately, the Dungeon Finder rule system is much more “intelligent” than you might think: players who abuse the system may find that they are removed when their tank compatriot leaves, regardless of how long they were already in the dungeon.
