To be fair, a lot of class animation look like an amatuer trying to use their weapon for the first time, especially if you pause frame by frame during GPose

Samurai probably has the worst skill animation ESPECIALLY if you compare SAM's animation to other video game features katana wielding protagonist such as...

MGS Revengeance
Raiden and Jetstream Sam

Nier Automata
2B

Sekiro Shadow Die Twice
Sekiro

Devil May Cry 3/4/5
Vergil

Especially when it come to a more traditional katana/kendo animation design, SAM's animation like an goofy adventure holding a katana for first time and decided to add as many flashy effect as possible to make up the amateurish animation, while Sekiro's animation is less flashy as FFXIV SAM, I will take Sekiro's Mortal Draw over SAM's Ogi-Namikiri any time and day
