If you are not willing to create a lfg, then sure dungeons are dead. But if you create a lfg, it will pretty much always fill in minutes. I have finish Dungeoneer last month and had no trouble finding people for any of the dungeons. Be willing to explain to unexperienced people, and runs will mostly be smooth. So yeah, if you wait passively then the game is not worth it. But if you are being active, this game is excellent.
