If it's too much, pare it down.
If it's not enough, punch it up.
If you're a player and don't like the game, play something else.
If you're a DM and don't like the game, change it.
This "I only play RAW/PHB/DMG because that's the right way" attitude is abhorrent. There's no reason to be polarized on any aspect of the game because it is, ultimately, what you make it.
Any DM who doesn't houserule to make the game what they want it to be is simply lazy. You put in the time, you craft your story/world/adventure/campaign to suit you and your players. If you find your lvl 15 PCs fight like lvl 10s because of limited access to items then you can do any of a number of things to fix it. Give them better items. Give them better spells. Feed them level 10 encounters, even if you have to craft your own opponents to make it happen. This argument is entirely about dissatisfaction at the game system not forcing everyone to play one particular way.
Even if you would have to craft an entirely new game system from the ground up to enjoy a night at the table, you are your only obstacle to doing so.
