Addendum: another aspect to the problem with this weapon mod: how would the target even know the other ship is using these? Assuming it even mentioned the weapon modification in the component list of another ship, and not just "rail gun", you would have to check the loadout of any ship you encounter in a fight in order to know whether your shield cells would screw you or not.
The idea of a hard counter to shield cells is sound. But this is not just a counter, this is a "gotcha" gun that may very well make shield cells mostly useless because you must always be prepared for the other ship to have this weapon modification.
Also: only a minority of all players even read forums etc. Imagine this weapon mod going live, and a random average player gets attacked with it. Cue email to support with the bug report "activated shield cell, shields instantly failed".
