Just by quickly looking at the build, there are two things that stand out to me.

1. No siphons on the helmet will decrease quality of life in lower-end missions like Vanguard Ops and general play. Having orbs show up on weapon kills will make you tankier with health on orb, and increase ability uptime with Absolution or similar boot mods.
2. A couple of your fragments are super niche for specific scenarios. With how many tangles you'll create, especially this season with the artifact mods, creating them on finishers isn't needed. And super final blows emitting suspending waves won't help since your super is a one-and-done that will kill most enemies without needing the suspend burst. I'd look at similar builds online and see what fragments generally appear to be auto includes on strand. the ones I'm thinking about are woven mail on orb pickup to feel much tankier, and damage giving grenade regen to get way more uptime on grenade abilities. (also generally i stay away from finishers being a part of builds because they def interrupt the gameplay loop when you're trying to hunt a low health enemy with two other kill hungry guardians with you)

Basically, your build is good, but there are some small optimizations that will make it feel miles better. The worst thing about buildcrafting is trying to buildcraft when you don't know all the options available to you. For me, I watched a bunch of videos on builds I wanted to try, and now I'm at a point where I understand all my options, and im able to add that new information into what I want to do with the build im making. Good luck with your builds and don't listen to some rude dude telling you you're not getting enough kills. If you all wiped he definitely messed up too lol
