Sockets in s2

Random question/observation.

I noticed that all helms/belts/bracers from raid(tier helms too) come with a default socket. Even from the Curio vendor. Is this intended? I see from the vault vendor that there’s still an option to buy sockets. So are we to assume those are just for crafted items that’ll need socketing? Or are we meant to use those socket items from vault vendor to add sockets to necks/rings unlike in s1?

Definitely unintended, since they made a new vault vendor item for this exact purpose. (S.A.D - Socket Adding Device)

Magnificent Jeweler’s Setting will be the staple all expansion, so no getting rid of it.
