Oddly enough I haven't found here the build I'm using for this Wolfhound... Anyway, this mech is really easy to play: move around, hugh a shelter and keep on poking and focusing on components until everything in your field of view dies. If anyone makes the mistake to ignore you, you will core it's torso / side torsoes with a couple of strikes. It is cooler than it looks thanks to the "-10% Energy Heat Generation", but it's still too hot and pretty useless to use ER-LL despite the additional -5% to heat gen for ER-LL... I would not use ER-LL for 3 main reason: You will overheat earlier. Cooldown sensibly longer, which leads to slightly lower DPS despite the overall higher HeatPerSecond. Despite the bonus to range, often you are fast enough to relocate / flank your taget. With good skills, you can have an optimal of nearly 500 meters (499 meters with my skills) Skill wise, max out both speed and heat generation / management (cool run, heat containment etc.). Anything else should be in range and survivability. Two Coolshots and one airstrike are recommended for this build. Top damage or up to the 4th place will be granted if you friendlies are not as squishy as marshmellows.
Lower the head armor and arms and put in a XL265. Forget speed and go left side for the armor quirks. https://kitlaan.gitlab.io/mwoskill/?p=jsonbin1.5bd594f8716f9364f8cca251#s=Sensor Systems
This build has been made obsolete by new tech: 6xERML is better despite slightly lower maximum DPS and range, because it has better speed and better sustained DPS.
This is one of those cases where having 6 hardpoints instead of 3 (for example) makes it worth using all of them. I found another mech build (Zeus 9S) with 6 laser hardpoints using only 3 for large lasers, where 6 ERMLs was obviously better for heat, weight and DPS. Large lasers make more sense when you run out of hardpoints or ghost heat for medium lasers and there is weight to spare. For the Wolfhound, spare weight is an issue but energy hardpoints are not.
With the new DHS might ERLL be worth a revisit for viability? Built it with the -1A here because of shorter laser duration. but the -2 for better heat is probably better. XL225 with 3DHS is just one slot short, but a TC1 is possible for +3.5% beam range. Alternatively, the -1 has +10% energy range, which makes it possible to out-range clan ERLL as you described.
Maybe with Light ferro and by further stripping armor it could be worth it, but I honestly don't like the idea of having such a slow light due to not optimal hardpoints and decent at best speed... It could be worth it in long range maps, but I'm not sure hardpoints are good enough for free trades against other snipers. Raven 4X can do a very similar job with 2xERLL, including 10% range and 10% duration quirks, plus JJs and maybe even a TC1. True, alpha is lower, but has greater sustained DPS, better speed / agility, better hardpoints.
