I am skeptical about using FOV Autoaim. How precisely does this work? If the FOV autoaim is set to something like 0.5 degrees, then it is quite possible in a dogfight for the lead indicator of the target to be in the autoaim FOV and the target itself to be well outside. It seems only rational that the lead indicator of the target would be the point at which the FOV autoaim fires, but there seems to be very little in the way of a technical explanation of how it works.
Convergence is even stranger. Does a ship with +Converging Autoaim also require $Convergence in the ships.tbl file? Does it require the "Gun Convergence" flag in order for gun convergence to work? If Autoaim FOV and convergence are used in unison, will the shots still converge at the distance of the target's lead indicator even if the player misses?
In designing my campaign/mod, there will be a few occasions where the player must use long-range primary weapons to snipe enemy turrets from kilometers away - and it would be nice if this did not require the player to have a high-end gaming mouse. Giving the destroy subsystem command to similarly equipped allied AI units might work, but again, the player should be able to participate in this directly, no matter what control configuration they use.
I really just want gun convergence so heavy assault fighters with widely spaced fire points aren't useless in a mid to long range dogfight.
