: Heres my take on the different ranks for the prometheans. The crawlers have
: the normal ones and the spiky tougher ones. The knights have two variants,
: normal ones who usually have scattershots or incineration cannons and
: black ones which have binary rifles or incineration cannons. In general
: the knights are a lot tougher and act more as high ranking enemies for the
: prometheans, equivalent to the white and gold elites. The soldiers have 3
: variants, the normal ones which pretty much only carry suppressors, black
: ones which carry light rifes, and big spiky ones which carry splinter
: turrets or scattershots. These 3 ranks seem equivalent to the elite
: minors, rangers, and majors respectively.

: For the covenant, well I've given up on ranking those so I end up
: prioritizing them based on weaponry. Also, it seems that the different
: ranks have less impact on their deadliness, with a gold elite being just
: as powerful as a major or minor.

: In conclusion, I agree that they need to vary covenant armor more and maybe
: even make the different ranks have a noticable difference on the
: battlefield. Since they added the prometheans and especially in Halo 5 the
: covenant just doesn't feel as fleshed out and interesting to fight.

At least from a lore perspective, with apparently the sole remaining larger-scale contender to the mantle of the Covenant broken, its leader killed, I doubt it would make much more sense to go back to the more rigid hierarchies of Halo 1-2.
