I've been reading it weekly because I translate it, but if I weren't, I definitely would hold off for a while. Battles are better read in large chunks, as otherwise it seems like nothing happens, and this has really just been battle after battle after battle as there are like five million going on at once so it just switches between them.

I loved the flashback arc and would have been happy to have it go on a lot longer. I guess Isshin was already gone from Soul Society by then, maybe. Otherwise you'd think there would have at least been a mention or glimpse of him. I hope there will be more reveals about the past after the endless battle finally ends.
