That's the whole point: in those scenes a Fighter is pretty much the same as "anyone". In a mass melee the party 'face' might be pretty much the same as 'anyone' while the Fighters whale away and do their thing.And what, exactly, does the Fighter contribute to social scenes that isn't literally what ANYONE can do?
What you're not giving credit to is the concept that yes, in most situations anyone can contribute, even if not much. It's on the player to figure out how, and tha represents part of the challenge of play: finding ways to stick your oar in during situations where your character isn't necessarily intended to be front and centre.
