This ties mechanics to roleplay. I'm not really sure if I like it. I can see situations where a player wants to rp a character with a big focus pool but can't access it as a str/luck/gui maxer without any will/faith/san to write home about being told by people that's never met them that their focus levels are small.

I would treat that situation the same way with someone that has low strength stat-wise but roleplays otherwise, or someone that has low celerity but roleplays as dodging really well- it goes foul of having abilities your character doesn't actually have (as per Rule 3 on the old wiki, or admittedly more vaguely as per the new wiki and forums). There's already a connection for how mechanics tie to roleplay (redtails are lucky, glykins are immune to poison, etc). In my humble opinion, it is advantageous to have mechanics tied to roleplay, to better enhance them. Focus is a tangible thing in this world, and while it might not be literal discrete numbers in-lore, it is still a force measured by the game system nonetheless.
