In novice matches people just dont know what to do nidh.
When they leave them they use those strange builds as loadouts and ships are restricted in them.
But as others said.
Burst on Gatling. NO. Greased, sometimes lesmok, heavy or incendiary. But usually greased.
dual gatling also only makes sense if u intend to ram alot. If not you will miss the damage to kill the enemy once the armor is down.
Its a bid better than dual flak but the same thing. You miss one component of the kill.
