It seems to me that almost no ship or ship setup benefits from having a Gunner on board. Having one of the only 3 classes be merely situationally useful doesn't seem like a good state of affairs. I may be wrong. I HOPE I'm wrong. And I'd love to hear a reason why.
I'm waffling on how much I need to explain my position. It seems kind of obvious to me how much more utility an Engie brings in comparison. Just having the ability to more quickly rebuild / mitigate fire stacks seems / buff your weapon seems more useful more then one gun mod. Even if the Engie plans on almost never helping with general ship repairs, in a pinch the extra tools seem to be much more important then having a useful mod for a second weapon.
For clarification, I'm not talking about having a dedicated Gungineer. Nor am I talking about how the odd build here and there may benefit from a Gunner. 1 x Pilot, 3 x Engineers seems to objectively be better almost all the time, and I want to be told why I'm wrong.
