Comparison of the regular Gauss vs Light Gauss (LGR calculated at 0.50 second charge time); not considering damage/heat this time, as it is largely irrelevant to Gauss Rifles:
Gauss = 2.61 DPS, 0.174 DPS/ton, 660 optimal range, 1320 max range
Light Gauss = 1.45 DPS, 0.121 DPS/ton, 750 optimal range, 1500 max range
As can be readily seen, the Light Gauss is god-awful bad, having significantly less DPS/ton than the heavier Gauss.
The greater range of the Light Gauss isn't much of an advantage either, definitely not enough to offset its far inferior DPS/ton. In fact, it isn't until approximately 1040 meters range that they are equal in DPS/ton.
At that range, the regular Gauss is doing 6.36 damage versus the LGR doing 4.91, giving each weapon roughly equal 0.074 DPS/ton.
If the Light Gauss's only useful niche is 1000 meter+ sniping, it is pretty much a useless weapon.
What sort of DPS/ton should the Light Gauss have relative to the regular Gauss? Well, looking at autocannons:
AC2 = 0.463 DPS/ton
AC5 = 0.377 DPS/ton
AC10 = 0.333 DPS/ton
AC20 = 0.357 DPS/ton
Except for the AC10, the smaller weapons have greater DPS/ton than the bigger, in addition to greater range.
Based on that, the Light Gauss should probably have greater DPS/ton than the regular Gauss. To do that, I suggest reducing the cooldown from 5.0 to 3.0 seconds, which will increase DPS/ton from 0.124 to 0.190.
Comparison of Gauss to Light Gauss will then look like this:
Gauss = 2.61 DPS, 0.174 DPS/ton, 660 optimal range, 1320 max range
Light Gauss = 2.29 DPS, 0.190 DPS/ton, 750 optimal range, 1500 max range
Further, Light Gauss should have their simultaneous charge limit increased from 2 to 4. A 16 damage alpha is absurdly low, and 32 damage alpha is only 2 points more than currently allowed with a dual gauss build (while requiring some 48 tons without even accounting for ammo).
If the Light Gauss still requires further buffs, lowering its cooldown further may be required, and possibly removal of its charge mechanic.
At that point, it becomes close to the AC10 in characteristics, so comparisons to that weapon may be justified.
Technically, the Light Gauss could end up with better DPS than the regular Gauss, and still not be overpowered, as it would be more of a DPS than alpha damage weapon.
EDIT: adjusted figures a bit after testing charge time for LGR and HGR in the PTS; LGR seems to be 0.50 seconds, and HGR 1.0 seconds, versus regular Gauss at 0.75 seconds.
