So, what exactly was the objective there? I know he was basically trying to beat Zangetsu into submission, but it seemed like there were three different fights happening at once. First, Zangetsu says that only one sword out of hundreds can defeat him, and all the others just shatter. He even says that each sword represents one of Ichigo's weaknesses. But later on, Ichigo is fighting for 10-15 minutes with each sword before they shatter. What's the point of it, isn't he just wasting time with the wrong sword? Or was Zangetsu lying, and the real point wasn't to find the right sword, but for Ichigo to become skilled enough to win with a faulty sword? And then we're never shown how he beats Zangetsu and gets bankai!
