After the events of mists, with the trial of Garrosh, there was some inkling towards the idea that Jaina, after her change into being just a female version of her daddy dearest, that just maybe she was making a turn around.
This started what might have felt like a reformation for her after the writers did a 'one more day' on her, and I even got thinking hey, maybe they might have her be something like the old jaina, but just more thick skinned, which would have been a good turn out. Even with her in WoD, she didn't seem hostile to the horde just unsure, which had me still think she'd get better.Kalec ran up and held Jaina and went very still. Everyone was despairing, save for Anduin, who refused to stop trying to heal Jaina. Chi-Ji, now hovering above them, promptly stated that "The student remembers the lessons of my temple" and proceeded to heal Jaina and the other injured, giving them all the second chance that was intended for Garrosh. Jaina opened her eyes and looked happy. She also took Go'el's hand and squeezed it, effectively forgiving him. After the celestials explained that they would have allowed Garrosh to live so he could continue to learn and how he was not the only one that was on trial, they told them that they must now go back out into the world and do what they must. All heads then eventually turned to Go'el and he humbly spoke for them all, stating that they would find Garrosh.
But nooo, after reading this (Spoilers) seems like Jainas had another personality relapse.
Next thing we're gonna be seeing Jaina making a magical covern called "Sorceress Frequency", where other female mages talk about how they are oppressed, despite not being so.Jaina is present at the Broken Shore, fighting alongside King Varian Wrynn and Genn Greymane. In the aftermath of the battle she attends Varian's funeral, and is outraged that the Horde left the Alliance to die against the demons. Jaina pushes for a front against both the Legion and the Horde, arguing with Velen over it, and says that her mages will never work with the Horde again.[18]
When Khadgar asks the council of six to let Horde mages back into the Kirin Tor, Jaina refuses. The council holds it to a vote and she is defeated 4-2. Feeling betrayed, she teleports out of Dalaran, leaving the Kirin Tor in Khadgar's hands.
