Play T5 Auric STG and Maelstrom exclusively. I linked the builds I use in this post:
All these focus on being flexible and survivable while having enough leeway to specialize in something. If any of them interest you, lemme know if you have any questions.
For the DMR and sniper builds you can reliably use them with headhunters or the kant12/1a for the sniper build as well with some tweaks. Mk3 or mk7 both are valid choices. Let me know if you want to know what to pop on those or the kants. The officer build also synergizes well with headhunters.
I’m constantly changing up the sapper build, so it’s the weakest of the bunch.
