I feel like when Vali and Issei reach Dragón God level the others Will be weak to them to consider them rivals. Imagine being Sairaorg or Cao Cao and seeing that Issei and Vali are strong enough to match Great Red or Ophis. In the end those guys Will have to realise they cant compete with the Heavenly Dragons. The greatest threat to the Heavenly Dragons i feel Will be Crom Cruach and Ingvild.
