Gladiator's Riot Blade not Comboing into Rage of Halone

[Bahn]

Is anyone having problems with this combo? No matter what conditions I try to do this under, when I activate Riot Blade it does not start the "Combo" buff like Fast Blade does. Nor do I notice any difference in my accuracy when I combo into Rage of Halone.

Also, from my understanding, combos actually make it so that the entire chain after the combo starter in the chain costs zero tp (at least, this is how it works with the Fast Blade --> Flat Blade and Fast Blade --> Savage Blade --> Goring Blade combo). This doesn't happen when I try to do Riot Blade --> Rage of Halone, which makes me think this combo isn't working.

Riot Blade's description and the patch notes indicate that there's no "Combo Starter" for Riot Blade, as Riot Blade IS the combo starter, so am I missing something here?

Edit: Nevermind.
