Would not make more sense to call the Azog in the movies Azog still and call Bolg his son Bolg 1. Why not make Azogs father Azog The Slayer. This would make both the movies and books make sense and cooralate. All the things Azog did before the battle of Azanulbizer was actually Azog the slayer, who was killed in the battle. Then Azog the defiler his son killed the dwarf king and avenged his father. All the events after this are actually Azog the Defiler and his son Bolg is Bolg the first. Why not use this instead of Azog in the movies actually being Bolg. This makes way more sense. It would be nice if this would be used instead and soem names were changed
