What did you find on doing burst upgrades on missile turrets? I've settled on using nothing but missile turrets and drones. My upgrade priority has been to get 5 drones, then get burst on both turrets maxed, then get a second ship and repeat. After maxing out burst, I'd then max out hull damage. Missile range is quite high, so I can stay at a distance and take out the enemies.
Accuracy doesn't seem to be an issue since the missiles can maneuver. I wanted burst instead of anything else to help the missiles get through enemy defenses more-so than an attempt at increasing damage. For this reason, I'd still take two missiles even at the cost of a bit of recharge time.
