An alternate build you could do if you don't care to SPAM the threadlings is to replace devour with hellion and focus your armor mods on grenade regen. I prefer this when I want to focus on putting in work with my guns while still having strong ability uptime, but it does take away the ability to endlessly spam abilities with zero effort whatsoever.
You can also work class items into this, but that's more up to your discretion.
Class items that have been nice so far -
Osmiomancy / Swarmer
Osmiomancy / Star Eater
Inmost Light / Swarmer
Inmost Light / Star Eater
