(Ninja) Why is Hurajin and Thing?

[Shurrikhan]

Hurajin is not button bloat if it has uses, niche as they would be.

The capacity isn't bloat. That it takes an additional button, though, arguably is.

Consider:

<Ability A>
Delivers an attack of 220 potency.
280 when executed from target's flank.
Additional Effect: Grants 30s of Huton duration, to a maximum of 60s.
Combo Action: Gust Slash
Combo Potency: 320
Flank Combo Potency: 380
Combo Bonus: Increases Ninki Gauge by 15.

With just that tiniest of changes to Armor Crush --raising its uncomboed potency faintly and changing it from extending Huton to granting it, via an Additional Effect instead of Combo bonus-- would there then be any reason to have a separate button for Huraijin?
