ditch corrupt light and savagery asap, switch to supreme cannon + desolation instead. The final build uses recoiler though, but alternatively, a hammer + repulsor will suffice as a substitute. If you happen to get a dawnblaze in that span of time, try and build towards dawnblaze + flaminator, which bullies low ranks due to the amount of corrupt light spammers there are. You should also ditch nightmare as a heat torso once you get windigo or molten plasma vest, the former being a poor man's version of the latter being the most overpowered torso in the game.
