The game played in the American League is inferior in terms of defense, personnel allocation and strategy.
Baseball isn't about hitting, and only people who have a very young child's understanding of the game think it is.
We can certainly disagree but you don’t have to be a moron about it.
Roger Maris' 1961 record of 61 home runs in a single season has been eclipsed a total of six times ... all of them by grotesque, steroid-enhanced clowns in the National League (Bonds, McGwire and Sosa).
Go figure. So much for the NL's superiority of "defense, personnel allocation and strategy."
Ah, but casual fan interest in baseball is all about hitting. All about action, not dramatic tension. MLB cannot attract a new generation of fans who grew up on video games and violent movies with 1-0 pitchers' duels, even if the old-timers have learned to appreciate the strategy involved. And MLB are having a lot of problems getting millennials interested in their sport.
The DH will eventually come to the National League. As mentioned above, the players union will never allow the AL to do away with it, so logically it follows that the rules for both leagues will one day be equalized.
