I fear for the hypothetical moment when the manga reveals that Shanks acquired the power to release a Griffon much later after his duels against Mihawk, in a similar way that Shamrock can release Cerberus, and this questions him being a "swordsman" as some claim
If Oda uses these mythical beasts to make these guys not be "swordsmen," it'll annihilate the whole fandom
