Excellent ideas, and while I may not agree with them all, they would ALL add more depth to the game. +1!
A thought came to mind when reading the internal item rarity section (sparkle beams). I'm an avid borderlands player (xbl) and in later content pushes for borderlands 2 they added another rarity tier to items. Perhaps instead of creating such stringent internal rarities amongst legendaries, why not add another tier of items, "angelic" for example? You could tie the cool skill runes and other amazingly cool properties to "angelic" items, and not drown out other legendaries. In my vision of a utopian diablo, these ultra rare, and guaranteed to be good items would be bind to account. To maybe tie this in without requiring another tier of item might be that existing legendaries have a chance to be "angelic" on drop (kinda like ethereal in diablo 2), and will spawn as a guaranteed good version of that item, maybe spawning with a skill rune or other incredible stat... But still be bind to account. This way you can add more variety AND have some rewards for actually finding your own gear.
