When filler is watchable, grow up if they did the time-skip now the animation would suffer and all we'd have is people bitching about that instead of filler. So enjoy wife Vanessa for the meme and go re-read the manga.
But there is no character development in them. And character development can still be filler because Dbz and Naruto have both used filler to expand on offscreen moments without torturing their audience with this lazy nostalgia crap. I'm ok with filler but at least do something original so it's actually entertaining. Even as infamous Naruto filler is atleast they try to put some original ideas in there filler instead of relying on old ideas, old characters, old jokes reused in crappy episodes.
There isn't going to be a time skip in the anime, we're getting a training arc instead so Tabata can get some distance with the Manga. He did the time skip in the manga fully intending to flesh out those six months in the anime, so like it or not it's canon character development for the next few weeks.
