With his heavy weapons he is able to destroy midfielders quickly, heavier with certain shots, and if he is not the target of many LARMs (try not to stand still and become an easy target), assaults will overtake you. Light as for most assaults are a difficulty, but if you hit a single shot ...
Welcome to mechspecs! Build link was almost correct: Code: [MEDIA=smurfy]238|11c968435a30c2dc42c5e176388b84557127becd[/MEDIA] Don't forget to check the FAQ About the build itself, it can be further optimized. FerroFibrous has the same slot consumption compared to EndoStell, but the latter will always free up more tonnage. Targeting Computer will only improve projectile speed and crit chance, but it will increase optimal and maximum range of beam weapons (any laser). General rule of thumb is to never use a Targeting Computer bigger than mk1 because it will be very likely wasted, with very few exceptions. In this case, you can fit a faster LE350, strip a little armor and downgrade to TC2, but it will become overall cooler. https://mech.nav-alpha.com/#5cad89ea_KGC-000 Don't forget King Crab has multiple cooldown quirks, so overall you will be shooting earlier and if you permafire this build will be hotter compared to what smurphy states. "True" cooling efficiency, as MechDB confirms, is around 53%, so it's still very cool but not too much cool like it would be with a 61% cooling efficiency.
