True, but the Executor wasn't designed to attack multiple Mon Cal cruisers at once... much less to defend itself from that many. It was a Command Cruiser, many Admiral disliked the idea of wasting money on such a ship whne they could have built about ten or twelve Impstars. Piett was also very authority-minded. "I have my orders from the Emperor himself. He has somethign else planned for the Rebel scum. We are only to keep them from escaping." He had been to told to do nothing, when the Rebels started to engage the Impstar at point blank range Piett had to improvise a defense because he didn't know what to do, he's fearful of the Emperor. His incompetence... Dude pointed out that he just lost the Executor and some support vessels. just the loss of the executor was reason enough to call him incompetent. His decisions were late. As for the support vessels they were Imperial Star Destroyer... How could anyone just lose that many Impstars to a handful of Rebels with Neb Frigate, CorCorvettes and some Mon Cals, and not to mentio that the DS destroyed two of the biggest Mon Cals at Endor...
