You misunderstood me. The question is:
Does it make sense that
one of a ship's mass drivers fires
faster than
one of another ship's mass drivers, just because the first ship has three MDs total (two of which are not being used) and the second ship only has two MDs total (one of which is not being used)?
In short, does it make sense that the number of mass drivers which are
not being fired has an impact on the refire rate of the mass drivers which are being fired?
If I give a ship 50 mass drivers, the single-gun mode would fire 25 times faster than the Ferret's single-gun mode, since the Ferret only has 2 mass drivers. Do we have any reason to think that's the way it should work?
No. It makes more sense that single mass drivers fire at the same rate no matter what ship they're on, and that the refire rate of multiple linked guns is the one which depends on the total number of guns.
Even if the other way around did make sense, someone would have to go back to 1990 and tell Origin that for me to change it.
