Assuming you're referring the DH as a "pitcher" (I could be wrong), I'll say that I like watching a pitcher bat even less than a DH. The pitcher Ab is a non-athletic play and shouldn't be in the game. Ironically, I don't like the DH rule much either, and the obvious solution is to field 8 batters. However, that'll never happen because of the havoc it'll wreak on baseball's record books. If I had to choose between a DH rule I don't like and one ninth of all at-bats being non-athletic events, I'll take the former. Again, I don't like the DH, but the alternative is worse given the unwillingness to adjust lineup size. As for the HR increase, it's not the ball, it's the launch angle revolution more than anything: https://www.cbssports.com/mlb/news/home-runs-are-back-in-baseball-why-were-going-to-see-more-homers-and-strikeouts/ .
