I used to agree with you about pitch counts, but now I’m not so sure. Look at how many pitchers these days have fastballs in the high 90s. That used to be a rarity. I’ve come to accept the fact that the human arm is now being stressed to the point of its physical limits, and what you’re seeing is surely a symptom of that.
A point I'd not considered. Still, if a pitcher is going into the sixth or seventh inning, still pitching strong and getting batters out, why change? I'm far from a baseball "expert" it just seems to me if a pitcher is still going strong why not leave him in? A good coach knows when a pitcher is getting tired and will replace them when needed.
Watching the last World Series for example was like watching one big pitching rotation in a single game. Dugouts got used up, pitchers were tired, etc.. How about some strategy instead of straight pitch-count?
