In competitive play (and high level PUG queue), the DWF, TBR, and SCR are still the dominant 'Mechs in their weight class. Strong quirk buffs to IS options such as the BNC-3E, TDR-5SS, and HBK-P have cut the gap somewhat, and given IS players alternatives, but they are either not quite as strong or restricted to a single role, compared to the Clan options which can successfully fill 3 each. Why ? Because Clan Tech inherently conveys massive advantages for small disadvantages (Clan XLs can survive side loss, Clan weapons lighter and longer ranged, easier to squeeze in 2-crit DHS, free CASE, etc.).
IS/Clan balance is as close as it has ever been, but there are a few notable issues.
1. The advantages of Clan Tech still appear to slightly outweigh even the best quirk sets available to the IS.
2. Many mediocre IS 'Mechs got very mediocre quirks, and are still very mediocre.
3. A few Clan 'Mechs (notably the lights/IFR) are severely hurt by the restrictions (namely inability to swap engines, locked equipment on low-free-tonnage 'Mechs) of Clan Tech, without any positives to compensate.
4. Others (namely WHK, SMN, etc.) don't have quite the ability to benefit from Clan Tech as the dominant 3, and while they can compete with nearly any IS, they aren't Timberwolves.
The solutions are simple.
1/2. Better quirk buffs to IS, especially those that are still struggling. Specifically, keep in mind that range on lasers is very strong (due to the hitscan nature), and is comparable to a range AND speed buff on projectiles. Moreover, cooldown reduction on hot weapons is nearly meaningless, while heat reduction is invaluable. Cooldown reduction on cool weapons is fantastic.
3/4. Give some mild buffs to weaker Clan chassis, tied to omnipods that aren't as strong (the Adder and Kitfox for example are less bad than most people think, since at the very least 4xSSRM6 is fantastic at shutting down deadly IS lights, but struggle far more with the non-missile pods on).
For all these tweaks use the DWF/TBR/SCR as "baseline" top tier - trying to get other 'Mechs to their (unquirked) level via quirks, but not surpassing them.
If TTK is way too low (due to increased weapons performance), increase hp again by 25% or so (tweak until its about right).
