I don't understand why you have a problem with Strada and Crom being as strong as they are. They are living legends so their strength should be justified. Strada was mainly a wall for Xenovia and Arthur from the events of volume 19. Crom is there to be a wall for Issei and Vali. Think about it, Ishibumi stated that Crom is the only dragon (besides the Dragon gods) that can challenge Issei and Vali. Vali and Issei strongest forms are already so strong to topple gods so we need at least one dragon left strong enough to challenge them. What's so bad about that? Sure Vali, didn't beat Crom but he didn't lose either. Their fight ended in a draw. If Vali defeated Crom than how would that look for Issei? He would just be getting Vali's leftovers. Vali and Crom needed to remain undefeated for Issei.
