Yeah, but Bahamut is the king of dragons, it has his reasons, but not all of them, actually you don't get all the GF of a battle.
For example Phoenix, you never battle him, neither Eden, Carbuncle or Siren, and they are a great help to the team (in my case, Eden Carbuncle and Siren make a great team with my Diablos and my Cerberus)
