I like the joint training arc a lot because the seeing 1-B in action as well as some cool new moves from 1-A was great to see, and the matches in general are great. However, I will forever be salty at the fact that Momo's team was the only 1-A team to lose, and how Horikoshi really... wasted her potential. Again. There are positives to it, sure, but it left a bad taste in my mouth and gives me the impression that Horikoshi will only have her ever play the role of a support hero when she should be able to do anything. Yes, there's still room for growth and perhaps she'll get there one day, but it doesn't feel like it given how he's been writing her.
BakuGOAT stomping, though. What a spectacle that was. Disappointing to see Setsuna and co. not get their chance to shine and all, but it was entertaining nonetheless because of the insane efficiency at which Bakugo destroyed the enemy team whilst making sure his teammates were all safe.
