Maximum stack for passive?

Q activation isn't a stance. However, the Apocalyptic Form 's Q  is.

Stance means to be kept as an passive as long as the user don't change stance. That also makes PBE Sona isn't a stance champion anymore.

E Apocalyptic Form isn't a stance cause of the activation effect. It breaks the theme (or at least I think it does).
