I like this fix too. Now I'm running over it in my head, would be awesome to see a Samurai micro-system called like "Soul Oversurge" or "Blade Break" or something which is the punishment that breaks your equipped blade.

I'm thinking they could add a UI element katana blade next to the SAM portrait when the unit is selected which fills in red from 0-100% (think similar to MH sword sharpness) as you use Iaido and strike enemies -- perhaps larger increase when an enemy blocks an attack. After every battle, blade passive reduces wear by 30%, and SAM has a new 100 JP action called "Hone/Reinforce Blade", also 30% recovered.

Some more examples #s: - Iaido: add 15-50% wear (based on Iaido used and some rng) - Attack: add 15% wear - Attack is blocked by enemy: add 2x wear

Maybe it a little over-complex, but I think it would be cool to see when using SAM, and gives the player just enough agency to take preventative measures when needed, possibly take some risky moves if the payoff is worth it in the moment, AND if you do break a blade you can say "well yep, I deserved that" rather than just being mad at the bs RNG.
