To be fair, it's only the total damage output that's limited, and that's against one target. Considering this though, the ships are most likely to dodge or evade the shots, with even battleships doing quick firing runs or passes against each other to minimize damage while maximizing output with fire control for the fleet or flight as a whole. However, if we want ships to take more hits, I would advise we lower the limit, assuming we stick with Wes' original version of the rule. Alternatively, we could go with the misinterpretation of the rule to similar effect since most ships aren't always able to bring all their weapons to bear.
