Long range weapon may be worth it if you regularly find yourself shooting enemies 1 km away or more.
I think you are wrong about overcharged weapon for pulse lasers. Grade 3 will give you 15-38% more damage at the cost of 35-70% more distributor draw. It seems like a lot, but going to beams from pulses will give you 30% more damage at the cost of something like 500% more distributor draw. Overcharged basically turns your pulses into beams without the crazy distributor draw (though it is still increased). I think it may be worth it.
Ok, it's not as bad as a beam laser, if you apply it to a fixed pulse laser it takes it down to around the DPE of a gimballed...

C3 Fixed Pulse DPS = 21.62, DPE = 7.56
Level 3 mean Overcharged DPS improvement = 126.5%, Mean drain increase = 152.5%
New DPE of modded weapon = (126.5/152.5) * 7.56 =
6.27
New DPS of modded weapon = 21.62 * 1.265 =
27.34
For reference a standard C3 Fixed beam DPS is
30.33, DPE =
5.37
So the overcharged weapon is still a bit more efficient than a beam.... but it's not exactly amazing.. Also, that's the mean, if you roll the highest DPS on your level 3 upgrade you get something very close indeed to a beam laser...
EDIT: And what about a C3F Burst laser? DPS=
24.97, DPE =
7.09 New conclusion, don't bother
downgrading your pulse laser with OC 3, just buy a burst laser which has almost the same damage but is quite a bit more efficient.
