Role difficulty
Opinion varies as to which class is the hardest and which is the easiest. Most agree that the Valkyrie and Barbarian are the easiest classes, possibly followed by Samurai. Some say Wizards are easy, due to their good starting equipment, but others find them tough, due to their bad starting equipment. For this reason, Wizards are often "rerollscummed".
Most find the Priest's innate ability to detect the BUC status of an item a tremendous advantage, and most find the Knight's code of conduct cumbersome.
Cavemen can be considered a harder version of the Barbarian, while Rangers and Rogues are often placed toward the harder end of the scale.
Monks are a unique class whose early game is relatively easy compared to its tricky midgame, mostly due to Master Kaen.
Healers and Tourists have a reputation for being extremely difficult, due to weak starting attributes and poor equipment.
