If you compare Rapid Fire on a C4 Pulse Laser to Efficient on a C4 Beam Laser, you'll see that the Beam Laser has 10% more damage and 15% better DPE, plus it doesn't have the added jitter. Plus, the Pulse Laser has 7 heat per shot, compared to the Beam Laser's 4 heat per shot.
Basically, the Rapid Fire engineering effect is never worth using, even before the jitter is added, since a Beam Laser will always do everything the pulse laser can do, only better. The same applies for the Burst Laser, which actually ends up slightly worse, because Rapid Fire doesn't enhance it as much as Pulse Lasers.
What if Rapid Fire gave lasers +100% minimum falloff? So lasers would start to fall off at 1000m instead of 500. That would give Rapid Fire a nice niche as a mid-range weapon modification, allowing them to be quite effective in the 1000-1500m range, but rapidly losing effectiveness beyond that range. This could be contrasted with Short Range, which is only really effective from about 500-1000m.
