If you can devote a slot: Rapid Fire Missile Launcher. I asked about this in the discussion forum and the feedback pushed me to buy it off the Lobi store. I gave it a shot (pun intended) and had way Way WAY too much fun using it.
I know BOff abilities affect them, but I do not think consoles do - and who cares! That's a lot of pew pew in a 180 degree arc
So, if you want "fast" shooting, it'll be worth 200 Lobi - even for a little bit.
On my Fed Cruiser I use both. Which I never had much issues with them. On my KDF I use photon only since I'm packing more cannons. The Fed Escort I'm building has Quantum since the other slots is more cannons.
