But, you know...your 4E PHB mock-up is spot on for me. So we can't be THAT far apart in tastes in the end.

Which is why I'd like to hand that question back to you, if you don't mind.
We're not far off at all. Being at work, I can't sugar coat all my posts and I may tend to be a bit short at times. When I'm home like now I can better get across what I mean as I have more time. So I'm sorry about that.
Anyhow, the reason why I was annoyed with your post is because there are a lot of people out there who complain about D&D as it is and should just play another system. I abhor those people and would never even suggest that D&D be gutted.
My sacred cows? Here goes and I'll try and be a bit less long-winded.
The Dice- D&D isn't D&D without a d4, d6, d8, d10, d12, and d20.
Classes- Other people like classless systems. Not me. You can certainly do classless with d20, but not in my D&D thank you very much. And I better see a Fighter, Wizard, Cleric, and Rogue in every version of the game.
Mechanics- d20 is used for attack rolls. Higher is always better. AC, HP, Saving Throws, and Levels are paramount and must stay.
Magic- Spells are broken down in levels. There is a split in magic between Arcane vs. Divine. Whether its Vancian or not, I don't care. Just give me magic. And of course we need boat loads of magic items.
Monsters- We still need monsters especially the ones that were product identity in 3.5's SRD.
Gameplay- Needs to be the same. Travel with a group of misfits, kill monsters, take their stuff. The game doesn't rely on miniatures or other visual supplements, but they can still be used to enhance gameplay.
For me, that's really it. Now when writing
Violet Dawn a lot of these things were the first on my list to change, but as core D&D this needs to be in there.
Stuff that I could care less about and what I mean when I say don't prior editions hold you back:
Half Races- For the love of god let statistics for them die. You want to play a high-elf? Fine. Your stats are those of either human or elf. You choose. Your character's looks are up to you.
Magic Missile- Any spell that auto hits at 1st-level is broken. And having a Brooch of Shielding repel it? Dumb. Can we get a mulligan on magic missile please?
+1, +2, etc. Magic Weapons- Lame. My magic sword should shoot lightning or be wreathed in flames. If you want simple + items make them items of quality.
Spells- Detect Evil, Locate Object, etc. See ya spells that ruin games. Save or die effects? Bye bye.
Random Generation- You want to "roll your character" the old fashioned way with ability scores, hit points, and gold? Fine have at it. But don't require it. I want point buy and fixed hit points in the book. In fact, keep both as some people like that.
