I don't think it's absolutely necessary for Katana Master to cater to duelists who want to make use of Vent Petale.

That way we don't have every duelist being katana + spear because there's no reason not to.

It is not necessary but it would be a nice option instead of being locked to only two handing a katana or double katanas. It wouldn't be more popular than the two handing setup we already see. I highly doubt every person would switch to Vent Petale Kensei just because.

Vent Petale is just the way to go currently on duelists thanks to a bunch of changes to skills that now cost 4m but are still worth it to use regardless, so I could very well see vent petale Kensei just being the optimal way to run it, this concern is very real and not one I can disagree with entirely.

As I said earlier, a spear that counts for it coming out eventually would probably at least help in that matter.
