If you're going to opt for ranged peak DPS in a medium, you should give yourself jump jets. Also, reallocate the armor away from the head since the chances of being hit their, and even being hit consistently there, pale in comparison to other parts of the mech. If you wanted to keep the extra 2% heat efficiency, you could drop extra armor in the head and arms, and 1 per leg to add a jump jet. I personally don't find this build to take advantage of the design's benefits. EDIT: This is also a IIC-A build, not a IIC-C build.
