Kubo wanted to end Bleach with the Aizen fight but Jump told him it was too popular and wouldn't let him, said if he ever wanted to be published with them again then he had to keep writing.
(Jump has been known to pull this *expletive deleted* for many years, Bakuman even pointed it out in a few chapters; the MCs are told if they want to write something else then to find another publisher, they solve their dilemma by pushing two publications through at the sometime and making the new one more popular.)
Needless to say everything since then has felt forced; little to no character development followed be anti-climatic fights.
I would not be surprised if Kubo is intentionally making Bleach as boring as possible, while meeting Jump's demands so they'll let it end this time.
