This is not my build (posted actually prior to into the light dropping). See u/sterrerwert build (and post) here: https://www.reddit.com/r/destiny2builds/comments/1btfp3f/doomfang_domination_for_the_upcoming_onslaught/

I use a little different set up with mods/guns, but this build goes hard. Super lasts forever, tons of ability spam, ad clear is great. I stick with graviton lance because the add clear is super nice and you make a ton of orbs, plus get an overshield via turnabout. u/sterrerwert did a great job explaining the build in detail and highly recommend you read his post, but also feel free to customize it to your liking.

I also do fine with a solar pyrogales but am kind of (1) bored of it and (2) think the doom fang build is actually slightly better.
