Should everyone get the Critical Ring?

Now that Nexon is giving everyone a critical base of 5% and apparently it can be increased by ways other than SE or Thorns, is the critical ring bbetter for every job now or should warriors and mages still get the other rings?

(This bishop has a 45% critical base without SE or Thorns.)
