I love that you feel this way. I wholeheartedly agree. Perrin is my favorite and the one I identify with best. I really wish we got a better idea of both sides of every argument there with Faile. I too feel like if we got more of her perspective earlier in the series, Like in Dragon Reborn even...
She really has all the potential to be a powerful foil for Elayne and just doesn't get any screentime to show she's competent at things or has relationship anxiety like Elayne dose.
I very much feel that this is where RJ remembered he had a third lead character in Perrin. I also maintain that readers would be more accepting of the forces relationship friction if we got any pov time with Faile leading into Winters Heart.
