Of course not. I'm not the one (nor would I ever) advocating/championing opposing party argument/parley fidelity or believability/coherency per our experiential (in our lives) derived model of parley or whatever you want to call it.
I don't see how anyone ever reading my words on these boards would think I am.
The games I run are undergirded by genre logic, thematic potency and coherency, dramatic impetus, and what is required to make a TTRPG work.
So I don't give a crap about Face NPCs securing parley victory at an Alice in Wonderland rate. Not only don't flinch, it NEEDS to happen for functional, thematically coherent, dramatically fortified TTRPG play.
But I simultaneously don't flinch at martial PCs doing all of the "unbelievable" things I mentioned above (I mean...they can wade into mortal, melee combat against Ancient Red Dragons and somehow survive and slay the beast) right alongside those "unbelievable" Face PCs! Not only don't flinch, it NEEDS to happen for functional, thematically coherent, dramatically fortified TTRPG play.
