I experimented with quite a few loadouts over time and I still am. Those are my current favs. Always tried to focus on good primers and detonators, less on weapons. Turned out items with max power level are often inferior to those with great perks.
So if you got that +250% gear dmg on a masterwork, use it and pass on that legendary with +30% weapon dmg. At least, that’s what I do.
The Ranger – don’t really like using it
The Storm – used to be my 2nd favorite
The Colossus – took its place
The Interceptor – still the best
