Yes, Critical hits are needed. As I have grown more senior and hopefully educated. I am a firm believer. I also value a more systems related approach to damage in naval games instead of a degradation mechanism. Critical hits are the best way to represent this, unless you go to a Star Fleets battles type system. This also fits in with my reading of damage results in combat in the WWI, and WWII periods, it also fits in with my experience as a SWO in the US Navy. System failure, and damage is generally a result of a single cause, not a thousand paper cuts leading to issues. /Jeff
