First things first- You need a different torso than the intercepter. It is not good for heat. The Zarkares, or the Windigo would go great with that.
Secondly, get rid of the flaminator. It is not neccesary, and makes you vulnerable against energy.
Finally, with the flaminator removed, change the modules. Replace the energy capsule with an iron plating, which you should bring to epic before putting on.
(Note: In order for this build to be good, it is essential that you take the zarkares (or a windigo if you get it) and put it on the mech. It will have much more heat, health, and energy.
