User blog comment:Salubri/Zanpakutō vs. Zanpakutō (Ryūjin Jakka)/@comment-5398287-20140202032418/@comment-44061-20140202150045

Id point out that having someone else wield the personification of your own soul makes no logical sense even in this fictional setting. (thus the aberration behind the bankai stealing medallion, which is not included) Rules and guidelines have been established in this series. Thus the point is to showcase if ones zanpakuto alone is capable of battling anothers. The fact that everyone in this particular case is beat out is just a reality of the facts. Not all Zanpakuto are created equal and the fact is Yamamoto's is the most powerful of its type and possesses the greatest attack power. These aren't interchangeable weapons nor is this something where everyone starts off on the same playing field. You go in with what you have.
