I'm looking for a decent medium-ranged build that's fairly versatile. My thought was, for a junker, Artemis on the front with Gatling/Banshee (or Mortar) on each side. We'd approach from a distance, using the rocket launcher to take out their systems and distract with fire, then sweep to the side to bring the Gatling (to strip their armor) and Banshee/Mortar (to smash their hull) to bear. The identical loadout on each side would give us more flexibility on where to engage, and the wide arcs on the guns could even give us a chance at a triple-assault.
I know the Mercury would probably be better on the front, but I rather hate that gun (firing it, not just being killed by it), and it wouldn't be as useful once we'd closed in anyway.
