Cie Qyu, if I were to change it into stance, it wouldn't hurt to change some parts of the active into persistant effects. For example, her W's range bonus can be a persistant effect, while her attack speed bonus lasts for, per say, 3 seconds. But this is up to debate.

As for the Rammus though, it is true that this was what I had in mind. If Rammus could do both...powerball + defensive curl = armored powerball? That aside, I didn't want Niina to be a ability spammable champion, since her Innate does help cooldowns per ability activation. Hopefully this explains my point...a little better.
