Here's what I'd suggest if we are going the route of giving Kensei Offensive Skills critical hits:

- Reduce all Kensei Offensive Skills to 3M.
- Swap the bonus for using a Katana from "reducing the Momentum Cost by 1M" to "this skill can deal critical hits for 25% extra damage." (This would hopefully have the side effect of giving more weapon options without making Katanas redundant.)
- For Wazabane, I think the Katana bonus should instead be switched to a damage bonus (that is also doubled while Airborne vs non-Airborne targets.)
- Swift still grants lightning criticals but if using a Katana, it gives 10% extra Critical Chance and Critical Damage (since you'll be able to crit anyway.)

e.g.

Kagekiri
Kensei Combo Skill. Dash forward in a 3-5 size line, and slash all around you faster than the eye can see, dealing Slash damage. If the sword you are using is a Katana type, this skill can critically hit, dealing 25% extra damage.

Wazabane
Kensei Combo Skill. An overhead slash at a target within 1 range, performing a basic attack on them with bonuses to Hit and Critical. If the sword you are using is a Katana type, this attack also deals bonus damage. While you are airborne, and your target is not, the bonus Hit, Critical and Damage from this attack are doubled.
