I would consider that stuff needing spot-fixes at best, rather than part of (again, as described) a "review...of the entire system top to bottom," which Lanefan has doubled down on that meaning exactly what it sounds like, calling it a "comprehensive review" and specifically expecting some things in a "needs-a-complete-rebuild" category.
The "math-fix" feats are an area I think most players just had a different understanding of how things were supposed to work. The designers wanted fights to get (mathematically) harder at high levels, so players would have to make use of their more-powerful abilities and synergistic effects in order to rise to the challenge. IOW, the designers were specifically trying to avert the "treadmill" effect in a very mild way. Instead, people reamed them for it, so they relented in the only way that could preserve their original intent while letting people address it if they wanted to.
Most feats weren't that bad--nothing nearly as bad as Pathfinder's Death or Glory, for example, and AFAIK nothing hitting the lows that 3.5e did--though I grant that there were some that just weren't really worth it 99% of the time. I don't, personally, consider that a breakdown of the system. There should be some value in learning what are good feats and what are mediocre feats, but there shouldn't be gaps like the difference between 3.5e Natural Spell and 3.5e Toughness.
I don't find any value whatsoever in forcing people to learn how to screen out the dogs in trait selection. The only virtue 4e had in this area was that it had baked in capability to swap out if you did do that.
So you need to have a totally comprehensive, encyclopedic knowledge of everything contained in the entire game before you even begin preparing to play? That's patently ridiculous. More importantly, it will guarantee the eventual death of the TTRPG hobby. Ain't nobody got time for that.
Every time I haven't had a pretty good gestalt understanding of a game system before starting to run it, I've come to regret it. Every. Single. Time.
It was satire.
Not something I consider any better an idea that hyperbole in online discussion.
