Well, if a time jump is going to happen, I kinda hope they just sorta make the whole jump, it would be a little like a second start to the series. Flashbacks are inevitable, so I guess we'll just have to suffer through them, but I rather not see a flashback to a portion of the training we already saw if it staggers. With a single large jump, hopefully, the only flashbacks we'll see are the ones like the Itachi one in the last arc, all new material. I really hate wasted panels on things I've read before.
