Hi!
I wanted to bring up the fact that on a LOT of ships, gunners are not very useful. They get to carry 3 ammo types and reload a tad faster.
There are a few guns/ships strategy that require multiple ammo type, but on a lot of set up, the benefit of switching ammo type is not as great as having 3 engineers that can chem spray, buff and repair your ship.
A lot of experienced captains fly mostly 3 engineers.
I'd suggest to buff a bit the class to make it appealing again. Maybe a reduction in jitter, a default faster reload time, increased damages, or something?
