A shitty tier list based primarily general damage output.

S: Nukor

A: Bramma, Kohm, Ogris (personal fav)

B: Hind, Karak, Dubba Stubba, Brakk

C: Quartakk, Chakkhurr, Kraken, Seer

D: Tonkor, Drakgoon

E: Shildeg

Nukor is straight up brain dead cheese. Build it for itself or as a status primer for melee. Doesn't matter. It needs a nerf.

Bramma/Ogris are both great AoE options but also have knockback, so beware.

Kohm go brr

Hind/Karak feel good if you want that classic AR or halo battle rifle feel.

Brakk is like a nukor without the aoe. All the status effects.

Quartakk can pump but it felt very awkward to use. Would be B tier otherwise.

Chakkhurr was also slightly clunky to use in missions. Quite nice single target however.

Tonkor/Drakgoon still do decent damage but very much suffer from having an overall slow rate of fire.

Shildeg suffers because the hammer stances/combos suck giant doodoo when compared to other melees. Still probably pumps because that's what melees do these days but when compared to other melees its in a bad spot.

No real idea about the Dubba Stubba, Kraken, and Seer. Not my cup of tea but based on potential damage output alone that's roughly where they should be. Also no clue as to where to even place the Ayanga. I very rarely use any archgun besides the Mausolon and before that came out, the Imperator Vandal.
