So what? Im not even talking about the planetary destroying laser array on the dang ship, im talking about its mobility, man power, armor, shielding, and battle force. Your also forgetting the EMPEROR, who in; The book of the sith; States IN HIS OWN WRITINGS( written by author from Sidious' PoV) he can maintain force maelstrom on the battlefield INDEFINITELY and re direct any incoming energy or matter to WHAT EVER IS SHOOTING AT HIM in the form of force lightning or throw. Also in the EU through deep meditation Sidious could destroy or manipulate STARS and SYSTEMS physically WITH HIS MIND, and stars and systems ARENT even confined to his OWN GALAXY.
