I don't know if this will break my NDA, but I tried playing these three dungeon during the beta. Our party managed to finish the dungeon but dying thrice on Fungal Grotto, thrice in Spindleclutch, and more than five times in banished cells (having incomplete party). A good challenge because there's a trial and error involved, and coordination between the party members is needed. Not the RUSH with DPS and healing power kind of thing some MMOs have.
