The best arcs of Bleach were the first two, where his editors made suggestions ad helped him finalize ideas but for the most part let him do what he wanted to do at a pace he was comfortable with—I think the only hard demand they made was to not drag his feat if he was planning on switching to an overarching plot instead of staying monster of the week.

After that he had differant editors who made more demands of him and we know that some of those demands led directly to the problems in later arcs.
