I don't see any impact at all, frankly.

First, we're almost 90 days out from release and still no "morphs ++" which means Dawn is static and hardly usable for me.  I don't like her appearance, nor do I like lots of her body parts - oh, those shoulders and that joker smile!!!!!!!!  Ack!

But, one huge impact she DID have is busting the "lots of vendor support and lots of products available on day one for success" myth.  No other figure has EVER had the kind of support Dawn got, and she's STILL a bust; has YET to de-throne V4.

And, quite frankly, I don't USE V4, so there's certainly no "favortism" here towards Vicky.
