It was proabably mentioned because it helped my point - Kubo sometimes doesn't know how to handle situations, thus show only the end of it, and we're afraid this is what MAY happen with the rests of the fights. Nobody 'bashes' arc here(I mean, not me as long as you don't take my words of this whoe "war" starting to loose its steam) Rose's and(to some extent) Byakuya's* case validates my reasoning, so no need to get so defensive.
Still as you see in my previous posts I voice the hope that I'm wrong.
It's just the doubts are 60% and hope is 40%, because several good chapters(Yama showing off was really badass moment. The start of the war was "ok" to me) hasn't convinced me that Bleach is back on track. It's ok to me for now(guess I should change my vote from 4 to 6).
*I'm skipping Zaraki's part here because in his case I believe we'll get some kind of explanation.
