The bunting was an example. If the MLB higher ups that that more bunting would appease what they wanted to see, they would institute rules to make bunting easier.
All I can tell you is expect to be floored, stunned, any other adjective you want to put in describing your disagreement with me. Watch any game when shifts where allowed, the 3rd baseman is playing 15 feet from 2nd base. and the batter was still trying to pull the ball. They did that because of their inability to bunt. Instead of forcing the batters to learn how to bunt and let the game adjust organically, they force through changes covering for inefficiencies. Every left-handed pitcher balks on pickoff attempts. Instead of enforcing the rules in place, or making a simple adjustment like putting a 45 degree line helping the umpires determine foot placement, they make a massive rule change limiting PO attempts.
Lastly, your statement about players trying to maximize every area of improvement comes from an (evidently) lack of understanding of the nature of professional sports. Players do not maximize all of their abilities, they maximize the ones that will make them the most money. Right now that is pitchers throwing hard, not pitching, and batters hitting home-runs, not hitting. When the cost-benefit of those items change (and they will because they always do), they will focus on other areas.
In EVERY professional sport, technology is changing how athletes and teams prepare. The NBA has seen huge rise in 3 point shoots because of the shot value. The NFL has seen less reliance on the running game for similar-type reasons. Those leagues are not making changes every year to "fix" those perceived issues. They are letting the game adjust and change before making massive changes. The MLB has been much quicker to use new rules to fix perceived problems then other sports in letting the athletes and teams work through these changes on their own. (The NFL makes dozens of rule changes every year, but most of those revolve around player safety and technology usage).
