I think that the problem is not the neutralizers. The problem is using the accumulators.
Accumulators is required absolutely for all. (Why?)

I think that need to depart from the concept of "all modules use the accumulator."
Energy produces a reactor. It should feed the main system.
Let us introduce for example the "heat"? Lasers shoot and produce really many heat. If the robot overheating, the guidance system should work badly (for example).
The game should have more characteristics than the hit points and the accumulator. Neutralizers should be usefull against one.
