The bigger the up-front damage, the bigger the crit damage. There are 1x, 2x, and 3x multipliers for crit damage. A roll of 2x from a single 5-damage slug (isAC/5, isUAC/5, isUAC/10, cUAC20, LPPC) or a 3x from a single 2.5-3.33 damage shell (cUAC/5 and cUAC/10) will destroy an IS DHS at 7.5 HP. A single 1x roll from isAC/10, any Gauss, or any full-size PPC will also kill an IS DHS (Gauss weapons cannot score 2x or 3x crits).
Lasers deal damage in ticks, and you need more than one tick to roll a crit to kill any components even if one tick rolls a 3x crit, which is why lasers do not crit things as often as PPFLD weapons.
Clan DHS are only more susceptible to a lower crit roll, basically, but it doesn't matter because structure takes extra damage, too, when a crit is rolled on equipment. That's why you will always lose your side before everything in it if what's critting you is anything other than tiny damage MGs, and even MGs often take the torso first if it's stacked with lasers and DHS and only do a clean out if there only two or three things in that torso (e.g. AC/10s, Gauss, HGauss, AC/20, etc.).
You can stamp your feet all you want over it, but you are not actually experiencing any significant DHS gutting and it's just not a problem that exists; a Clan 'Mech with cXL and 2x ERLL in a side willl have slots for 20 HP worth of DHS, 5 HP more than an IS 'Mech with an LFE and 2x ERLL.The real problem is Clan Gauss exploding 100% of the time on a crit and having only 5 HP to begin. That needs to get fixed, makes 'Mechs running cGauss in a side torso into Piranha food. Additionally, the big guns for both sides are too easily crit; even the IS AC and LB-20X with their 25 HP are evaporating immediately on an armor breach because the chance to hit them is so high (10/12 and 11/12, respectivley).
