Hey, I am too. But it's kinda a fool's errand to please everyone.And to better support the super hero tastes that some players and DMs have, it would be nice if WotC published a book that modified, augmented, or out-right replaced higher level martial features with more mystical/ magical super hero-like features. It wouldn't be anything I would be interested in, but I am for supporting people being able to enjoy the play style they want.
5e specializes in dungeon crawling. And they're business-oriented. Their deadlines mean they have to adjudicate their time. Any time not spent on bringing a better dungeon-crawl experience is time making an incomplete game. Honestly, it seems like they're already always pressed for time.
So is there any reason why they didn't bring more options for those types of players stylistically? Maybe not. But financially, the reason was simply crunch. We can't have it all. Limited resources, unlimited wants.
