Role-Playing
Sub-classes that focus more on playing a role rather than creating item, typically grant special bonus on action or unique skills when playing the game. Role-Playing sub-classes popularity is varied significantly because of their usefulness. Many sub-classes in this category fall in obscurity over time, for example, experience point bonus from Apprentice, price reduction from Merchant, and Berserker’s boosted state through skills attract more players than Housekeeper’s ability to clean up the environment when managing real estate. Not to mention that some of the tasks can be completed by employing NPC's as long as you have money (such as paying an NPC Housekeeper or Butler to manage your house or room in order to avoid penalty fees).
