Rune socketing system is kinda dissapointing

PoE 1 had crafting bench for solving resistance issues and even gear requirements.

I assume the rune socket system is ment to fullfill a similar job. Problem is I have play for like 30 hours and only found 1 currancy to add a socket.
To me that feels like a failed game design since we really need the ability to easily alter stuff.

Also ffs let us remove any runes inside a socket.
