What should I do now?

The primal fights aren't fun if you don't have a good group for them, and all they unlock is the ability to do more fights that aren't fun for the same reasons.

Basically you've done everything for now; wait until new content is released.

You think you want to progress because that's what is left to do, but it's not fun, so don't bother with it.
If your situation changes and you get a group, then try them out again.

I like that perspective. Never thought of it that way. (Side note: love the femRoe)
