We also know that the weapons, despite being lower tonnage, have drawbacks that have made them close to comparable ton-for-ton to IS weapons (c-ERML and c-ERSL notwithstanding). The longer beam times, burst-fire ACs, ripple-fire LRMs and higher heat means that 5 tons of LRM (an LRM-10) and 5 tons of c-LRM (2x cLRM-10) have roughly the same power in a fight. Now, there are some differences, but those can be bridged with small weapon balance tweaks along the same lines as what we've already seen.
The thing is that once you balance the weapons ton-for-ton, you'll still have a performance gap. You're trying to bridge a gulf that's simply too wide to be bridged with weapon tweaks alone, short of completely nerfing Clan weapons into uselessness.
Where does this problem start? WIth one thing, and one thing only: The Clan XL engine. It offers the same weight savings as an IS XL engine, with none of the drawbacks. The cXL300 in the Dire Wolf gives the same survivability as an STD300 in an Atlas, and allows the pilot to bring 9.5 tons more weapons to every engagement. The cXL375 in the Timber Wolf allows for greater maneuverability than an Orion with its biggest engine, an STD360, coupled with the same zombie potential and 9 tons of additional weapons. The cXL330 on the Stormcrow gives it the same survivability as a STD330 on a Shadow Hawk, with 12 more tons of weapons. The list just goes on and on.
Look at the Inner Sphere, and you'll see it. The vast majority of builds run an XL engine simply because the weight savings gets applied to more weapons, and the increase in firepower makes the risk of ST-death worth it. The STD engine does still exist in certain designs, such as the Centurion and the Atlas, whose primary purposes are breaching enemy positions and being hard to kill.
The Clan XL essentially allows for the extra weapons preferred by most builds, and lets them stay in the fight far longer than the average IS 'mech, just like a Standard engine would.
So how can we bridge this gap?
Simple: Look to tabletop. When a Clan XL engine has a side torso blown out, it loses two engine crits. This means that it generates 10 additional heat per turn. Since most engines contain 10DHS, this means that the loss of a side torso essentially reverts what's left of the 'mech to SINGLE HEAT SINKS. With the increased heat generation of Clan weapons, there would be very little reason to fear a Timber Wolf that's lost a side torso, since it would hardly ever be able to fire its remaining weapons.
When you add a massive heat penalty for Clan XLs losing a side torso, you'll have finally tackled the root of the balance problem... and you can make up the rest of it with weapon balance.
