Everspace 2 Interceptor crit build

I made a build focused on critical hits, and switching between 2 rapid fire weapons. Here's a quick n casual (failed) reliquary run, with the build showcased at the end. I should've played on nightmare difficulty so I'd have more drones to feed to the flak cannons.
Also! I realize I forgot to show the passives. Here they are!
Critical hits have a 20% chance to recharge Weapon Overdrive by 1%.
-Primary weapon hits refund 30% of their energy cost.
-Collecting an energy orb grants +1% increased critical hit chance for 6 seconds up to 20%.
-When flying towards a locked enemy target beyond 1500m range, gain +15% increased speed.
