With Shadowbringers, the loss of Enmity decreasing skills such as Diversion for DPS, makes it so it's almost impossible for Tank Chocobos to hold higher Enmity then the player using any DPS class, even should said chocobo have all 10 Tank skills, and set to Defender Stance, as such and in light of the new changes, I think one of the Chocobo Tank skills should be a new Tank stance like Dark Knight's Grit or Paladin's Iron Will, or at least having it set to Defender Stance would increase it's threat overall since it can only use tank skills in that stance anyway.
