While I agree with the Steel Wind Strike being an insult to put on a wizard and none of the martial classes, this is a bad argument because pretty much every anime swordsman who would pull out a shit like Steel Wind Strike as it is written, is explicit supernatural. I get your sentiment but this is a very flawed, easy to dismantle argument.
That would be a good point if this was an argument, and not just me bellyaching. Also, the supernatural side of anime swordsmen tends to be "They studied the sword so much that they've got these expert abilities" rather than "they spent long enough in the library to unlock these techniques".
To my understanding, I'm not a big anime person.
Nah, a lot of the anime are having their own magic systems - chakra, nen, stands, pacts. It's common to sometimes make mundane look like supernatural (Demon Slayer), but generally if someone teleports most anime would qualify that as a magic use.
Yeah, but there's also plenty of magical martial arts right, like hamon? DnD wizards have a particular flavour of spellcasting (int based, using a spellbook and weird spell components) which doesn't really fit well with stands or nen, right? Like, performing magic through sheer martial prowess rather than study and arcane research feels like something that DnD doesn't have much support for.
3.5's Tome of Battle, released at the end of the version's life had three Martial Casters that hit all the anime highlights.
The book was also notorious for being broken as hell, but I really wish they'd have taken what worked from it instead of just dumping the whole idea after 4.0 was a fan flop.

It had plenty of support for that in 4e. These days only monks get to be magically martial
I mean they are, half casters. But also it's a 5th level spell which means Rangers get it at level 17. No one plays at level 17 so basically only wizards get it.
If a warrior can withstand the tail weapon of an adult dragon without batting an eye, they should be able to perform Steel Wind Strike just fine.
Besides, nothing in SWS is explicitly supernatural, except for the "teleport next to one of the targets" bit, which could be flavoured as "you move really fast next to them".
That's why I've said "as written". I'm sure this was designed by people who hold the mindsets that doesn't do reflavoring (the recent feat allowing you use deck of cards as spellcasting focus from Book of Many Things is another good example) and also thinks Fighter and Barbarian and Monk are just "guys at the gym". Sadly same sentiments were in WotC since 3rd edition, hence why options martial should get were all given cringy anime names and relegated to new classes and explicit called magic by the text.
Which is the only way to stop people belly aching that they aren't as world defining as wizards. Magic will always have a bigger effect on the world than a guy with a pointy stick.
