Let's talk trained monsters. I want to know if anyone actually took the time to charm and raise a monster in this game to the point where there was actually a point in using them in place of a human character. Has anyone actually done this and found it better that way?

Side note... Mediator is the suckiest job, in my opinion. I hate using monsters in battle so there's no reason for me to learn how to charm them. The only reason they're any decent at all is because they can equip guns and you have Mustadio or Chemists for that! Bah.
