I've been giving some serious thought to how to work the Firespray and I've come to the conclusion that you need 2 together for mutual support.
One alone is not efficient, but I believe with the correct flying, they can be lethal.
I have also decided that the named pilots bring no value.
I am going to try this set up.
Firespray-31, Weapons Engineer, Shield Upgrade, Heavy Laser, Concussion Missile
Firespray-31 Weapons Engineer, Heavy Laser, Concussion Missile
You always have 4 firepower at any range and can put out 4 target locks. With some fancy flying and mutual support arcs I think you can really mess up your enemy.
I'll fly them this weekend and report back.
