I do think that you and others rightfully harbor a concern about the fighter's ability to influence the OoC narrative with their class abilities, and it's possible that Paizo did not think that it was of core importance. Hopefully there will be further clarification or information about that.
I'm less concerned about the fighter's ability to drive out of combat narrative, than I am about game masters that need explanations/hand holding for/regarding how fighting classes (without a lot of skills outside of combat) can drive RP or out of combat narrative.
