That one didn't bug me - in fact, with the exception of Leer, none of the changes bugged me. Maybe if MJ puts her away in an institution for being Bi-Polar - since he's not using her in LC3 anyways, it's be an easy explanation.
But seriously - I liked the militant feminist... and can't stand the royal snob in LC2.
I've been looking around, and I haven't found a model for Davros yet... but given what he is and how he's shaped, I DONT see it being a problem to get made. I'll ask around.
