For the 9002nd time, stop making sweeping generalizations about Clan gear. You cannot just shuffle every variant and weapon into a single bin of effectiveness, because their effectiveness wildly varies from chassis to chassis and weapon to weapon -- just like the Inner Sphere.
Clan Meta Chassis
Timberwolf
Stormcrow
Some Dire Wolf builds
Clan Meta Weapons
ERML
ERPPC
Gauss
SRM4
SRM6
^^That's it. Those are the only Clan things that are "overall better" than their IS counterparts.
Adders aren't overpowered, and are actually pretty terrible. Summoners aren't overpowered, and are really bad. Kit Foxes have niche roles of ECM trolling and 3 AMS, but otherwise are inferior to the good IS lights and mediums (which go nearly the same speed with more armor and firepower). Warhawks are roughly comparable to the good IS assaults, it does a few things better than they can while also doing a few things worse than they can. Novas are a one-trick pony that can only do one specific thing well, which is boating lasers; otherwise it's mediocre and not particularly tough due to meh hitboxes and mounting locations. Most Dire Wolf builds aren't overpowered because they're so goddamn slow and unagile; they have the firepower of a moonbase but they also have the maneuverability of one. Only the fringe builds like 2 ERPPC + 2 Gauss can qualify as being overpowered, and even then they can often just be sidestepped and flanked.
The LB 2-X isn't overpowered, and is quite frankly almost useless. The Clan LB 10-X and LB 20-X suffer the same issues as their IS counterparts, in that they spread damage and do don't enough damage to compensate. The Clan LB 5-X is the only viable one of the bunch, but that doesn't make it OP. Clan Ultra ACs aren't overpowered (unless you have a SHITLOAD of them). Clan Lurms are situational (more versatile due to weight and min range, but are more vulnerable to AMS and having only partial volleys hit [lose lock before all missiles hit]). Clan "Standard" ACs are just trash. Clan Flamers are equally useless as IS Flamers. Clan Pulse is terrible, excluding the LPL which is just barely passable but still not meta. Clan SSRMs have the same weaknesses as IS versions, but with horrid cooldowns on the larger tubes. The Clan SRM2 is equally worthless as the IS version. The Clan ERLL, with its 2.0 second duration, does basically the same damage "per second" of the beam as an IS Medium Laser...lol. The Clan ERSL suffers the same issue as the IS Small Laser in that it is completely and utterly inferior to its medium-class counterpart (although not to as large of an extent for the Clan version. but the gap does still exist).
The only Clan items that can qualify as "overpowered" have been listed above. Focus your efforts on tweaking those items and those items only. To put this into perspective, the breakdown above means that 37.5% of Clan mechs are "better" than the IS, with the remaining 62.5% not being so. This also means that 15.625% of Clan weapons are meta compliant while the remaining 84.375% are roughly on-par or even inferior in some cases (like the [U]ACs and arguably ERLL). Just stop with the sweeping generalizations for crying out loud.
