The cleanse provided by Cantus of Consideration when used by a Performer is.. awkward with Idol Step's Ally confusion.

Namely that Cantus of Consideration considers these 'bad' and will proceed to cleanse the charm you've given your ally, over.. Say..

Level 300 poison.

Or worse.

It's nothing major, just a pain considering the classes are supposed to synergize well and this is a point where they do not.

This isn't a bug.

I would also argue that certain negative status effects caused by allies, aside from the Charm, are useful to dispell via Cantus (such as Potion Sickness), so changing this behavior probably isn't a great idea.
