I honestly can't stand Jaina, she's gone from hating the Horde with a burning passion to forgiving them and recognizing the Horde as diverse with Garrosh being the true villian to hating the Horde to forgiving Thrall to hating the Horde. Like holy shit, it's like plot bipolar disorder.
At this point I hope she either just dies or fades into obscurity. Thrall at least has been somewhat consistent in motives and reasoning, Jaina is just all over the fucking place.
