Since Rainbow isn't really a thing anymore and Boltor Prime has apparently fallen off a cliff, I'm looking at Braton Prime for my next generic, boring, all-purpose rifle to cover short/mid range (my Lex Prime still covers long range).
Serration, Heavy Caliber, Split Chamber and Primed Shred are the main four, then likely Primed Cryo Rounds if going for Viral, or 60/60s if going for Corrosive, but if I go for Viral/Slash I'll also need Fanged Fusilade to shore up the Slash aspect for procs, and so I'll lose a precious slot and probably Vigilante Armaments with it.
So I have three options basically:
Viral/Slash only, with Vigilante Armaments and Fanged Fusilade
Viral/Slash/Heat, trading out Vigilante Armaments (or Fanged Fusilade if it can be dispensed with) for Hellfire
Corrosive/Heat with High Voltage/Malignant Force and Hellfire
My gut tells me to go Corrosive/Heat because of the way armor scales in high level content and it's very simple to build for, but I don't know for sure. My goal is to make the weapon serviceable in 100+ content and Steel Path.
(and I can dispense with Vital Sense and Point Strike, Braton P is not a Crit weapon in my eyes, UNLESS Hunter Munitions is a huge boon for it)
