please take into acount that my version would work only if minecraft had more content distributed beetwen the different ores, simply doing that without anything else would artificialy elongate the grind, its more of a 'for the future' suggestion.
-my idea is to make make moving from one toolset to another harder and adding more content beetwen them and to:
-make wood and leather more encouraged by elongating getting stone
-preferably make stone better since you'll use it for longer
-make copper necessary
-make iron the toolset for most of the midgame
-make gold a redstone and decoration exclusive since its not used for tools by anyone anyway
-add rosegold as an optional step between iron and diamond, rosegold would be crafted from gold and copper like in real life and add an actuall purpose for gold as a toolset
-make diamond the toolset that you should get for the enderdragon
-make netherite a bigger upgrade and easier to get, it should be mainly for post dragon content (like the wither and more if more gets added), if a sift ore will get added netherite should be a sidegrade with a different plastyle than the sift ore, probably for tank players
-a theoritical sift toolset should be balanced to be on around the same power level as netherite while being diffent, maybe it could have worse base stats but be for more of a swift playstyle
of topic but i love this game but the proggresion is terrible, i'd love to see a total revamp, albeit it would be very controversial
