I attempted the dragon quest (VON 5+6) last weekend with my 10 cleric and 11 other players (all level 10) and let me tell you it is no joke. We received a thorough beatdown before even getting to see the dragon, although we did make it to the boss before him which was this HUGE iron golem with lots of pets. This dungeon is filled with puzzles....big big puzzles, and some of them require seperating the raid into two groups and communicating effectively so that levers can be pulled at the same time (by party members with certain stat attributes) and things like that. It is definately not something that would work well with a pickup group, unless you somehow managed to get all really competent people who were willing to work together.
