This is what I typically use for LOOOGIN.
One of the most important things to know is that PBB flames get a boost out of rending, which you can get a 10% boost for 10 whole seconds on elite kill, which there is no shortage of on auric. This enables your guns to clear out bulwarks, crushers and whatever other armor comes your way by just spraying them while rending is active under PBB, it's a surprising amount of damage.
The Achlys twin stubbers are fun, but honestly they're kinda shitty because you can't actually use them effectively out of PBB, it's up often but it feels like dogshit without the active, and after defending the stubbers for years I can only strongly recommend you to try out the Ripper gun MK V instead, it just does everything the achyls wants to do except better, including clearing the entire screen of everything within an instant.
Melee weapon, and even blitz is entirely choice/preference. I take rock because I fucking hate mutants and it eases up your ammo usage for tagging the special that needs to die instantly, and you can already make a hilarious amount of space in an emergency if shit hits the fan by bracing and magdumping, but If you do take another blitz, drop bulletstorm under lucky bullet because honestly it's overkill enough as it is. The good shootin is a nice node to keep since it's an unconditional 15% crit chance on every shot
