What you haven't shown in any way is that visible numbers HAVE TO be present in every game.
They do not, but they are going to be visible in this game regardless. We are going to have perks that describe our newly-gained abilities. A number of them will also likely be math-based abilities (a perk that grants +20% damage, for example). Yes this simplifies the math the player has to understand considerably, but at what cost? It isn't like any cRPG system ever requires notable intelligence to understand anyway. It is Level 1 math.
Whether it's
comprehensible to the player isn't the issue. What they're describing is best summed up with a word that gets a lot of ridicule on the Codex, but nonetheless applies here:
immersion. They don't want to think of their character as a guy with a 14 Intelligence; they want to think of a guy who is decent at figuring out puzzles and spellcasting. Stat-centric players can still look on
the chart in MSH P&P and know exactly what it means to be Monstrously (75) Agile or Excellent (20) at Fighting, but the intention is to get the players thinking not in terms of number crunching, but of what it's actually
like to be that character: how you would describe it to someone who didn't know the game system - how you would read about it in a book or see it in a movie. They don't want you thinking, "Oh no! It's the Hulk! His Strength is 50 points higher than mine!" - they want you thinking, "Oh no! His strength is unearthly! He can even overpower the mighty Thor! I don't stand a chance!" The psychological difference is significant and important.
Anyway, I think I've explained this into the ground - if you don't get it by now, you never will.
