The turret arcs are a mess after 4.86 update, you should look into it
The buttom turrets should turne 360 degrees
The side turrets (not on the wings) should be able to look directly down
The back turrets should be like they were befoure mod update
Not entirely on topic, but the guy is right. We should be avoiding the tendency to nerf everything bigger than a snub. In a few years we'll end up with a situation where one battleship can be defeated with a long range quad nova tactical bomber that a certain part of the community will lobby.
