User blog:Niohoggr/NPC's character construction

On the novels it is said that when a guild conquer a dungeon then can convert it in their base and create NPCs to defend it. So when a player create an NPC have to decide their appearence, their level, their equipment and their classes. The power and abilities of the NPC works the same way of the players, so the job classes and racial classes are very importatn at the moment to create the NPC, but how is that the players choose the classes for the NPC. If the classes for the NPC construction are free to choose then all the players surely would choose strong and rare classes so I dont belivie that the dearest devs of YGGDRASIL would allow that, also won't be interesting or fun. So the options that I see to obtain or choose the classes for the NPC are: That's my opinion, what do you think that is the way the "shitty devs" programmed the system to create the NPC?
 * The players only can choose classes that the guildmembers have
 * There is a list of free classes to choose and advanced classes with some conditions, like pay real money or so
 * They need a special item to use in the creation of the NPC, something like racial change items to give the race class to their NPC and some kind of special item to give the race class
 * A mix of the previous conditions.
