True that, It puts all the characters in this light that makes you actually sit down and either really love or hate these characters, DOA1-4 didn't do that because of the weird story mode XD
Is not the plot nerf (though that is a bit upsetting in general), is just how immature she was portrayed and that in not a single point they showed her developing past it. She is just a bit too bitchy IMO. The game is great, and the story was nice in general besides that.
