You can disagree whether they are sluts (they are), but Layla is not the same character. Now you may like this slutty version just as much as previous, I don't. I have a problem between what story Nyx want to tell, and what story she actually is telling ( even with all character thoughts forced down our throats ). What seems to happen is Nyx wanted to tell certain story, the story she told was received in diametricly oposite manner of what she intended. All characters are different as Nyx tries to force us on a certain path. Now this would not be a problem, but there are so many plot holes that I fear we are in for another correction just before this story gets abandoned.That's not true... Layla's path is bascially the same it's been for at least 2 years now (not sure if there were changes before that) and I haven't noticed any major change with the other characters either.
Though the fact that you call them "sluts" kind of explains it... =/
