Had built up troop reserves for 3 regiments per planet when I went on my Death Star spree. After running on Fast for awhile to build the things the Rebels had sabotaged a good nimber of troops and shields. When I started using my DS's most of the galaxy went into uprising. This continued to worsen when rebel strike fleets bombarded trooper garrisons that had lost their sheild gens. Rebel forces were overwhelming sectors so fast that I went rapid-fire on the "Destroy System" button, killing 3 planets in 1 day. (This included Coruscant which had fallen to concentrated sabotage missions.) When the dust settled I was left with 1 major shipyard 20 battered planets and my 6 newest Destroyers. I was a noob back then. SO, all you newbies to Rebellion, learn from D16's experience(s), NO DS KILLING SPREES!
