I'd like to ask if you use any kind of rule to build your fleet and if yes which one. Given the fact that rapid fire is not working it seems more intelligent to invest predominantly in battleships, to have high enough firepower but even a high number of hits-per-turn. Destroyers seem to have a fire-cost ratio less convenient that battleships and death stars seem useless since their true power relied on the high rapid fire (too expensive to build in high numbers, so having a maximum of one hit per ship make uselss to have 200000 of power)...
