The Quincy plot was already introduced.Ichigo losing his powers after Aizen was a damn perfect ending if you ask me.
The only disappointment I had was that many bankai weren’t revealed. But what a big joke that Quincy Ark was. Destroyed everything.The Quincy plot was already introduced.
Many would have been dissappointed if Bleach would have ended after Aizen.
The only Problem was Ichigo loosing all of his powers. This way fullbring arc became a pain.
