One good thing about the Lost Dungeons is that certain classes that were previously underappreciated are now in much greater demand, simply because it is hard to complete the adventures without them. No party is complete without a Warrior as a sturdy meat shield for the casters or a Cleric as a dedicated healer and resurrector, or an Enchanter to mesmerize monsters when a party has bitten off more than it can chew. Rogues are a definite must if the party also wants to loot potentially trapped treasure chests.
