Seems just the opposite is true around here. I am seeing more and more purple Xenos each weekend. Most of the girls swinging them are coming from the blue 2013 Xeno. They look to be working pretty well, too!
Keep in mind when comparing a 2012 vs. a 2014 bat, that your DD is @ 2 years older when she received the new bat (assuming both were purchased new), so she is bigger, faster, and stronger!
I do not think composites need to be broken in any more. I think the Xeno is what is is no matter how many hits you put on it.
