Mearls was trying to woo the OSR community, including some of its most unsavory bunch, during the D&D Next design and playtest phases. These people gave their input, Mearls appeased them, and then they promptly ignored 5e and continued playing their preferred OSR games. But these aren't the people who are now playing 5e D&D in mass numbers. Most of the D&D "veterans" who play 5e are likely WotC-era players (e.g., 3e D&D, Pathfinder 1e, and 4e D&D) at this point.
Aside from one shady actor (ZS), I disagree.
But our disagreement doesn't matter.
Because:
Mearls was right to simplify 5e the way he did.
Lots of new and casual players have tried the game more than ever before. 5e being more accessible and newbie friendly if not outright helping D&D being played by more people than ever before, it certainly didn't get in the way.
Power creep just raises the bar of accessibility of the system to new players. Yes longtime players love the new switches and dials for their PC's, but it has no upside to bring new players into the fold.
I do think that the game would benefit from greater character customization at 1st level. ...
That is my knock on the "subclass". They only start at level 3, and they are a feat tree on rails. You make one decision at level 3 (But realistically everyone decides at chargen...) and then your done.
I think if the number of class feats
cough I mean abilities was properly curated they could have been made more free form in selection.
You would not have had an increase in system complexity, but you would have had more actual choices to make in your PC's advancement, which would make them more unique.
I personally wish that WotC would do away with curated class-specific spell lists precisely for this reason. Having more "power source" or themed spell lists (e.g., Arcane, Primal, Divine, etc.) would be easier for adding future spells with far less wasted page layout space on classes that get the same spell.

Not hard WotC. Just not that hard.
I am probably in the minority for not wanting classes to share spell lists. But you can't have everything all at once.
Baby steps...
