You get what you paid for here. A 70 tonner than cheaped out on the engine, energy hardpoints and locked standard armor. Good damage in the 400-500 meter band.
This is the version that I've been using. The heat from the HLL just doesn't dissipate quickly enough for me without the extra heat sinks. I also find that I've never run through 4T of ammo.
Ultimately, the thing that hurts this mech are its low-slung arms. It's not like the Night Gyr with guns bolted to the bottom of the pauldrons. I suppose the other thing is that the armor on the arms and side torsos feels paper thin for 70T, but that's why this build runs long-range weapons
