I brought this up last week and it looks like she hasn't gotten it down just right yet, it looks like she is pushing herself beyond what her physical form can handle at the moment. Going into the trance (White Phoenix) seems to transform her into a vicious monster but is it safe for her and those around her meaning those on her side. I don't remember Kyou Kai ever pushing herself except when it counts. The Zhao are no match for her so why go to the extreme, you know, save it for when you face a formidable foe these guys are small fry.
