Anyone who plays Battletech often complains that energy weapons are too good. The problem isn't that their weight-to-heat ratio isn't balanced in isolation but out of isolation the internal heatsinks mean it becomes way too good. I will focus on CBT because DHS makes these issues worse.

Let me show you the math.

Name, Damage, Heat, Weapon Weight, Total Weight after heat neutral, DMG/Weight Ratio

SL, 3 DMG, 1 Heat, 0.5 tons, 1.5 tons, 3/1.5 = 2

ML, 5 DMG, 3 Heat, 1 tons, 4 tons, 5/4 = 1.25

LL, 8 DMG, 8 Heat, 5 tons, 13 tons, 8/13 = 0.61

PPC, 10 DMG, 10 Heat, 7 tons, 17 tons. 10/17 = 0.59

Note: I have included enough ammo for 20 shots and used HBS damage values 5/8/12/20

AC2, 5 DMG, 1 Heat, 6 tons, 0.5 ton ammo, 7.5 tons, 5/7.5 = 0.66

AC5, 8 DMG, 1 Heat, 8 tons, 1 ton ammo, 10 tons, 8/10 = 0.80

AC10, 12 DMG, 3 Heat, 12 tons, 2 tons ammo, 17 tons, 12/17 = 0.70

AC20, 20 DMG, 7 Heat, 14 tons, 4 tons ammo, 25 tons, 20/25 = 0.80

Note: I include enough enough ammo for 20 shots.

SRM2, 0-4 DMG, 2 Heat, 1 ton, 0.5 tons ammo, 3.5 tons, 2/3.5 = 0.57

SRM4, 0-8 DMG, 3 Heat, 2 tons, 1 ton ammo, 6 tons, 4/6 = 0.66

SRM6, 0-12 DMG, 4 Heat, 3 tons, 1 ton ammo, 8 tons, 6/8 = 0.75

LRM5, 0-5 DMG, 2 Heat, 2 tons, 1 tons ammo, 5 tons, 2.5/5 = 0.5

LRM10, 0-10 DMG, 4 Heat, 5 tons, 2 tons ammo, 11 tons, 5/11 = 0.45

LRM15 0-15 DMG, 5 Heat, 7 tons, 2.5 tons ammo, 14.5 tons. 7.5/14.5 = 0.52

LRM20, 0-20 DMG, 6 Heat, 10 tons, 3.5 tons ammo, 19.5 tons, 10/19.5 = 0.51

All of them have reasonable Damage to weight ratios, those with lower ratios have the bonus of being harder hitting or hitting further. The problem is that the 10 internal heat sinks are too much, it leaves any mech with AC oversinked (consider the WVR-6R generates a max of 13 heat if they jump and alpha with 12 heat sinks) and makes energy weapons from good to great.

SL, 3 DMG, 1 Heat, 0.5 tons, 0 tons, 3/0.5 = 6

ML, 5 DMG, 3 Heat, 1 tons, 0 tons, 5/1 = 5

LL, 8 DMG, 8 Heat, 5 tons, 0 tons, 8/5 = 1.6

PPC, 10 DMG, 10 Heat, 7 tons, 0 tons. 10/7 = 1.43

In comparison, the damage to weight values for AC.

AC2, 5 DMG, 1 Heat, 6 tons, 0.5 ton ammo, 6.5 tons, 5/6.5 = 0.77

AC5, 8 DMG, 1 Heat, 8 tons, 1 ton ammo, 9 tons, 8/9 = 0.88

AC10, 12 DMG, 3 Heat, 12 tons, 2 tons ammo, 14 tons, 12/14 = 0.85

AC20, 20 DMG, 7 Heat, 14 tons, 4 tons ammo, 18 tons, 20/18 = 1.11

My fan rule change is reducing the free heat sinks from 10 to 5. Every other rule stays the same. You still get an extra free heat sink for every 25 engine ratings above 250 and need to place an internal sink for below 250. DHS still double the heatsinks. 5 free heat sinks instead of 10 means that the choice to jump or run is a choice instead of hopping around like a bunny on crack.

What do you all think?
