I just had a thought.
4v4s, or Crazy King,
Flak Fish Build.
One Pilot - Kero, claw, drogue chute - Move and stabilize.
One Buffgi - Spanner, Mallet, Buff - Buff flak.
One Maingi - Spanner, Mallet, Chem - lots of chem.
One Amazing Gunner (you) - on heavy flak, with Incendiary.
Incendiary Flak, at a good range, can put fire on four/three heavy Galleon guns, put fire on an entire pyra, put much fire on a junker, etc. etc.
Incendiary Buff Flak Fish with amazing gunner would make a hell of a sniper support/kill ship. Use Incendiary to enable disables. Use other ammos to kill. Would work great (better than flak spires) on crazy kings.
