That's fair, as far as it goes.
Hmm. Metagaming. Class is metagame, level is metagame, the numerical value of all your skills are metagame, your hit point totals, armour class, number of spell slots. All metagame. Real people aren't aware of numbers associated to arbitrarily assigned 'skills' and 'statistics' which somehow 'represent them'.
But according to Captain One True Way, you're not allowed to know or use this stuff to play the game. That would be bad and evil and you'd be playing wrong. It's literally the second rule of roleplaying. No, I mean, literally. Not figuratively. Literally.
It's eye-opening, hilarious and tragic all at the same time.
