Nah, hate the top-tier-centric approach
If anything, itemization should be fixed in a proper manner, not some “GG” over “Gg” over “gg” tier and have them differ even more…
Just - assign some role to an item type and have them excel at that particular thing, and have it so that people do what they prefer
- A levelable item - start with +2 or +3 to a certain skill, level it up to +8 (has one less affix rolled)
- A socketable item - has 1 less affix and a “socket power %” value, can hold one extra socket
- Chaos item - has increased inherent affix and Imprinted Aspect has extra levels assigned to it but cannot be Enchanted/Tempered/MW-ed e.t.c.
- Reforgable item - can be MW-ed up to 20 levels but no Temper
e.t.c.
Like, there’s no real or good reason why every item has to be succumbed to additional RNG, sure have some, but all ? 
As you can see, this can become a bigger topic/effort though… For now I think the better thing to fix is the Glyph system and paragon board
