The Power Circle
If you're Pyro go top tree for getting through the story, spec into weapon damage. Stack as much Bonus Firepower as you can. The tier II mod I mentioned earlier, Perpetuum Mobile and Mitigation from Death are absolute must haves. Abuse volcanic rounds along with mods and skills that affect Burn and Ash status.Yeah, I think I'll have to commit to a full anomaly build for Pyro.
I've been using a middle tree hybrid build and it's not as effective as it used to be. I don't have many tools when I get swarmed and Heatwave takes too damn long to cast
I didn't really figure most of this out until I was well into the story and watched some build guides - DPS is king and you can brute force your way through the vast majority of the content. I died hundreds of times but never had to drop my world level.
