AS7-D is one good Fatlas.
It beats the DDC in energy/zombie potential and it beats the S in ballistic power. So if you want to keep it you might want to capitalize on those advantages. If not, you might like better the RS variant for single AC20 or Gauss builds.
Dual ballistic combos have great DPS ,low heat , good range....the drawback is that you must stay on target. That said, suppressing enemies becomes crucial in order to minimize return fire.
You dont shoot and twist like with an AC20 Atlas brawler, instead you should keep your DAKKA on enemy (cockpit is prefered), untill he retreats, or drops down...
