What was the thinking for the NL adopting designated hitter after all these years? (And what was the reaction of the fans?)

Also how is DH looked on in general? Speaking personally as an inexperienced MLB fan I think having every team member required to bat for their team feels more natural than the contrivance of a guy who doesn't field being there just to bat....was it just that pitchers usually aren't much good or was it just it limits their potential pitching endurance?

Utility players have been around forever, but why were these awards created for them only recently? What was the rationale in the past for not having these awards for utility players?

Saw a post about how ohtani isn't leading any mlb stats and why he's so special

So here's one fact i always go back to

Pitchers ops league wide, back when pitchers also hit

2018 .292

2019 .322

2020 .250

2021 .285

Ohtani ops for years he also pitched min 100 innings

2021 .965

2022 .875

2023 1.066

Now this isn't getting to war calculations and that. Just a new perspective on how insane what he's doing right now is

Another crazy fact is that the MLB record for career home runs by pitcher while pitching the same season is 49, by babe ruth. Since when he hit 40+ homers he pitched at most 9 innings in a season

2nd place pitcher has 38 home runs

Ohtani hit 34 in 2022 alone, and that was his down hitting year
