Honestly what use was chiron, because he didn't do a lot in the books and we don't see him interacting with other characters so that could be a sign of favoritism and the guy gives off major Dumbledore vibes. His rules, like his punishments foe what would've happened to the Ares cabin after they attacked percy in ttl, aren't structured or good, and he kept hiding a lot from percy which made him even more vulnerable to the divine world.
