The game will never be simple enough for some players, nor complex enough for others. An unfortunate but true statement. The game cannot and will not be all things to all players.
However, I do agree with
@Shardstone that it tends to be easier to start with a simpler foundation and then let other companies build upon it, rather than have a more complex game and companies try to strip components away to create a simpler one. It can be done, obviously (as we have Level Up going in one direction and
@Sacrosanct 's game going the other for instance)... but I suspect that WotC will always try and split the difference. 2014E had some parts very easy and some parts that were more complicated, and 2024E will do the same thing (even if different parts get changed along the easy/difficult axis.)
The only thing I wish would be for players to finally get over the idea that they must play the "official game" published by Wizards of the Coast for it to count as being a "valid D&D player". That attitude is silly and unhealthy. If you want a more complex game, then just play
Level Up - Advanced 5E and you can BE that "D&D player" who plays a more complex version of D&D-- rather than stick with the "official game" you don't like and are constantly complaining that the game and its designers are unwilling for it to BECOME the game that you would like. To me... that's just cutting off your nose to spite your face. Just play the game you like more! It's fine! D&D is D&D, no matter WHO publishes it! Isn't that why so many got so hurt about the OGL debacle in the first place? What was the point in getting all bent out of shape about the OGL potentially going away if you don't consider any of those products to be "real D&D" as you constantly keep trying to push the 2024E game to become the game you want (even if it seems obvious that the game in those instances will never be)?
