I just started Hero Command Prestige upgrading for my Imperial Prestige. I upgraded so far for this acc:
HQ, Research Lab, SC, 3 Barracks, 2 Factories, 3 Transports, and Armory. After the Hero Comm, I will start the 2 vaults upgrading for Prestige Starship Command, and then the Depots for Prestige Shields. As it already was said, don't know if Prestige Shields can be a benefit or a problem, if that extra 1 range make easy reach the shields, and force a change in my current layout.
My Rebel Prestige still is upgrading Armory (4d to complete) and locked on defense. Next step also is the Prestige Hero Command.
Keep using my 5 droids to upgrade both dekas, the Safehouse and turrets to level 10 while both bases aren't maxed out yet. I stopped upgrading Units to Prestige after Jets-Jumps/Tanks, and I'm upgrading my Armory units now, like Jets to 7, jumps to 8, and Sullustan to 5, and also walls and heat sink for Bursts and Rockets for better in Heroic Defenses.
