Wolf - The problem is, if you only get additional HSs that output at 1.4x, you are correct, it doesn't make sense for bigger mechs to field them. If they were 2.0x, you'd need fewer HS (and thus fewer slots) to pack more weapons. My AWS-8V has 28 SHS, not because it was in any way efficient, but because I didn't have the crit slots for them. Here is the math:
28 SHS = 9 engine (240) and 19 non-engine HS, so 19 tons and 19 crit slots above the actual engine.
To get 28 cooling out of lame DHS, engine has (9 x 2 = 18 cooling), so I need 10 cooling / 1.4 = 7.14, rounded up = 8 lame DHS = 8 tons and 24 crit slots!!! Sure, I save a bunch of weight, but I lose a ton of crits to place stuff! Sure, I get a tiny extra bit of cooling, but at the cost of 5 slots I don't have. And remember, you need 3 consecutive slots to fit them into, negating CT and legs.
To get 28 cooling with proper DHS, engine has (9 x 2 = 18), so I need 10 cooling / 2 = 5 real DHS = 5 tons and only 15 crit slots.
So... the REASON that heavy / assault mechs generally HAVE to run SHSs, at least with heavy energy loads, is because running DHSs as they stand in many cases actually make it HARDER to add more weaponry to compensate for things like slower speed, etc. If you had proper DHSs, you could actually add some stuff to your Atlas that might HELP you compete with the little Cicada with it's 6 MLAS running circles around you. Which might actually make it somewhat worth the 1.5m CBills currently charged to get DHSs.
Actually, my point is that having 1.4x DHS is entirely not viable for heavier mech builds. Which gives lights and mediums a distinct advantage in damage, over and above the already clear advantages in smaller hit areas and greater speed making it harder to lead a target, etc. See my math above.
And if you argue that lights/mediums have less armor, fine, call it a wash with them being so much harder to hit. Then why do they still get the added benefit of being able to more effectively carry DHS?
