I've tried a build like this in arena and struggled with pushers. Anyone with a repulser, missles with pushback, the jump backwards distance thing, and etc. made me waste a movement to get back into firing range.
Just a guess but try replacing the torso with its energy counterpart, replace the top weapon with 2 distance shredders, and remove 1 resistance drain to fit an cooling booster in that last slot. You'll be able to fire ay any range and have higher max energy and heat/energy regen. Let me know if its good!
