Heavenly Dragons don't know Crom full strenght. Fafnir seems to be a lot stronger than Grendel (he s able to block his atack vol14 and *spoiler alert - go past lilith and rip off lucifer hand*) and there is a Vritra who is a king and evil dragon and he is the weakest among them. I'm awere that there are some extra powerfull evil dragons like Crom Cruach, Azi Dahaka or Aphopis so I'm wondering. But the thing you mentioned about noticing their limits was the most helpfull for me. Oh and in vol 14 Azazel still think they are dead so he only said something about sealing their souls.
