I find it pretty interesting how, except for Point 5, all these problems are pretty much exclusive to the anime. Like for #1, the whole ending bit where Trunks fights Zamasu with that Spirit Bomb Sword is completely anime exclusive, the manga version of the arc handles the power scaling so much better than the anime (although the anime version definitely has it's advantages). I definitely took issue with how Trunks vs. Zamasu was handled in the anime so I was really glad to read the manga version which still gave Trunks a moment to shine near the end, but in a way that made logical sense. #2 is also exclusively in the anime and thank god cause I hated that too, lol. I guess #3 is also in the manga since Kale still goes Legendary Super Saiyan, and Broly still happened but the manga skips over the Broly arc. It just kind of mentions it happened and then moves on. Though I have no issue with the Broly or Legendary Super Saiyan stuff. & #4 Hit doesn't improve his time-skipping ability at all during the fight with Goku (in fact, SSJ Blue Goku is so far above Hit in power the ability straight up doesn't work against him).
That said, I prefer the anime version of Hit, I don't mind him improving his ability mid-match, it's not like him getting stronger per-se just get refining a technique's potency. But it lead to him having better character development (him throwing the last match makes more sense in the anime) and made his relationship with Goku more interesting and endearing imo. They don't have much in the manga. And it made the fight more interesting, like with the Kaio-ken thing, Goku doesn't need that in the manga since it's not really that competitive of a bout in the manga. I haven't saw far enough in the anime to see how he does in the Tournament of Power arc, but considering they built him up a lot more in the anime, I'll admit if he performs as well as he does in the anime that's going to be disappointing.
