Well, of course in the movies, they required a lock-on for their lasers to converge. I recommmend this as a WEAPON flag rather than a ship flag; in short, it's another request for homing primaries.
Erm, yeah, to confirm what they were saying, not exactly homing.
Automatic Laser Convergence is a system that
changes the angle at which the lasers are fired so that they will intersect one another at the exact point of the enemy's ship. (There's NO "Homing" about the laser shots, PERIOD.)
Using the existing missile aspect-lock missile setup but creating a second aspect diamond (colored a separate color or at a different size) would be ideal for this.
Blindfire as shown in Starlancer IS Auto-Laser Convergence but requires no aspect lock; it is always perfectly locked on.
Therefore, it should be offered for both weapon AND ship flags, but use the same or similar code; that way if you want a specific ship to have built in convergence like Starlancer, then it can be done, or if you want the blindfire convergence to be inherently designed into the weapon for whatever reason, it can come with the weapon when put on the ship. >_>
I want this feature though very badly :3
As for imbalance, well, in Starlancer, a single hit from a blindfire ship's weapons didn't do NEARLY as much damage as hits from weapons on ships without it; so generally, if you have this auto convergence on a weapon the weapon ought to not be the best in the universe unless the enemies are god.
(Starlancer's blindfire WOULD NOT FUNCTION if you had two weapons enabled at the same time that had different ranges/projectile speeds. You had to switch to using ONE weapon only in order for blindfire to be enabled. Again, another option that could be customized.)
