If Destiny actually...you know..elaborated/showed how badass Crota/sons were...maybe then the Hive. All I know is...supposedly he can destroy a moon or something but stil canl be subdued by weapon fire....which the Covenant has far more advanced tech than the plebe--- I mean Guardians. So The Covenant...Plus they have Arbiter, he'd kill the entire hive with his voice alone. Kieth David..so good.
