Returning customer - question about CRs

[Zikke]

I haven't botted in WoW for a long time, but I am considering it again. Where did all the CRs go? It would be for raid combat rotations.

Is there a paywall now for CRs? I see there is a store; is that the only way to get CRs now?


Thanks in advance

Singular has improved a lot, but the other advanced CRs are either in the store or gone.
