I wouldn't call her crap, but I do agree there are better choices to be made. However, if you make a Zayne you are sculpting that figure and then who are you putting with him? Chances are you need a second sculpt to be made. Same with Jennir or any other recent comic book characters.
Hasbro is all about cost effective, so repack a Maul means the comic pack would only be sculpting one figure which is what Hasbro wants. But also, look at it this way. Hasbro doesn't like to waste sculpts either, so they can make this figure which gets out and sells. Then they take this sculpt to make other Nightsisters, slowly over time and it's a win win situation. If you are not a fan of this character or don't like it, then simple, don't buy it. I for one would love to have her in my collection.
