The dodo are "mini-bosses". Just because it isn't a humanoid or Dodo Qink, doesn't mean it isn't a "mini-boss". At higher ranked leves, the monsters you fight are roughly rank 34-39 and then the "mini-boss" will be rank 49. That is definitely a mini-boss to me. I don't understand what everyone wants them to add. It is only 20 minutes long.
