@constibetta it's for administration purpose, yes mc clears dungeons by himself but he also owns other dungeons now. So it probably has to do with handling paper work and stuff since hunters from other guilds will also want to use his dungeons. Also the dungeons he has are low ranked dungons which is a good place to train new hunters, so my thinking is that he'll charge it cheap so people come to his dungeon, thus hitting ares economically since they charge a heafty price to enter their dungeons.
@izayamikaelis My exact thoughts, I absolutely would not have let somebody with that as their predominant personality trade into my guild if I were building one based on purely trustworthiness.
