It helps to consider the context of the build itself.

The name is not indicative of its combat role. It’s a 3040s take on General Kerensky’s ON1-K
Orion; he likely wasn’t doing a whole lot of bodyblocking either. He was a “protector” in a different way, or at least, that’s how those who remember him and the SLDF within the Inner Sphere remembered them.
Of course, to reproduce his actual build in MWO, you need the
Protector (its stock configuration and very existence being apocryphal at best) and not an actual ON1-K, because of how hardpoints work. lol
