After reading this thread, I switched from Range to Freq cap on my FF. (I previously had it on damage.)
And for the first time I can remember, I ran out of clusters.
Bit of a non-sequiter, but if I usually don't run out of clusters it's because I'm dying which means that the extra burst I'm getting is winning me dogfights that I might've lost which means that Freq cap is the best which means that I'll need a fleet of ammo replenishing drones at my beck and call unless there's a ship with two whole missile bays that which can be unleashed with a fearsome thrust at opposition forces.
Or I'm prematurely making snap judgements based on the anecdotal evidence of one match.
