Why I HATE the universal designated hitter rule in MLB

In baseball, the designated hitter rule is the common name for Major League Baseball Rule 5.11, adopted by the American League in 1973. The rule allows teams to have one player, known as the designated hitter, to bat in place of the pitcher. Since 1973, most collegiate, amateur, and professional leagues have adopted the rule or some variant. MLB's National League and Nippon Professional Baseball's Central League are the most prominent professional leagues that do not use a designated hitter.
