Unlike you, I watch more National League than American League baseball. That's because I'm in the Philadelphia viewing area. FWIW, I'm not fond of the DH rule, but reasonable minds can differ. Each approach has both pros and cons.
Pitching appears better because an upper-cut swing is, as I said, all or nothing, so pitchers get more strikeouts than they used to. This is also why batting averages are down across baseball. A batter with an upper-cut swing has less probability of getting a hit than a conventional batter, even though the batter with an upper-cut swing is more likely to hit a home run.
