cool. So, legs are cool.
The issue is that you will lose a turn. Because the range 2 it is blind. Top weapon will be at range 4. Ok legs are cool but might have to jump for it. Players will exploit that. Sometimes will have to jump back losing the effect to use the axe.
Hmm, combined modules will not provide cooling and regeneration just higher cap. Your mech it is a heat mech which overheat your own with those weapons and also require energy without top weapon. Will need to be mart to play with.
