I have seen this option in other MMOs and I would like to suggest it. As of right now to get into a pug group for Dungeons everyone is reduced to Istan spamming techniques which as we all know isnt efficient. A que system that picks up players that are within the levels of each would be a very helpful feature. Another suggestion you could quickly implement until you get this done would be another chat channel for just dungeons that is world wide, that way we dont have to travel to LA and back to the dungeon a bunch of times to find people to fill in for a spot.
