This is not an uncommon sentiment. For me, it has often led to tinkering, house-ruling, and homebrewing. In its essence, this sentiment is the main reason there is a HAG blog at all (however infrequently I post here, the sentiment remains). Head over to ENWorld via the link to read the comments….there’s some sound advice in there.
The rules for each edition were slightly/heavily modified rules taken from a previous game. Sometimes they were easier to use or understand, sometimes not. As a result, they are simulacra or perhaps more accurately an eidolon. (See what I did there?) I feel like today’s D&D is a bit like heavily processed food. After a while I kinda crave something a little less processed. If they built a game from scratch to simulate(?) fantasy heroism(adventuring) I doubt it would resemble D&D. I understand why WotC wouldn’t do that though. I will definitely still play, because people play it, also I can and do still love the following.
Swords and armor
Magic and Fantasy
Heroism and adventuring
Solving puzzles and riddles
Monsters and characters from the various fantasy creators especially ones from or adjacent to D&D.
