i die a little on the inside everytime i see that word
it basically sounds like this
i find it interesting though tthat you mention skill progression but still mean there is no ‘‘classes’’ or somewhat crafting professions, i would assume there is, from what you wrote, but i guess thats a matter of definition.
worth mentioning, due to @KuroKuma constant complaining that limits would be bad i basically dropped the pick two and made the one i linked above, a ton of progression meaning it will be hard as hell to try and use only one.
Never the less, since its basically a reflection of a few of a my 15 different posts on crafting, it would be weird for me to agree with it 
Question though: you keep using the word ‘‘infrastructure’’ which by definition is this
which i feel is none of the above, so can you go deeper into that and ‘‘tooling’’?
