very nice well thought out i like it and would get this champ on release date.

It has been mentioned to me by a couple of friends to give her at least one other skin. I do have a skin in mind. And I suppose it works, but I would really rather not use this idea. Haha.. I have been thinking for another one, but in the mean time, does anyone have any suggestions?

while this is very long, that also means it's very detailed. I really like the distinction you draw between her two sides, like sides of a coin, completly independant and different, but both necessary to have the whole. I agree that the voice acting could easily make or break the champion, but if this was made into a real champ, i think riot would be able to pull it off, either way, this is very well done. One thing i saw, it feels like the points from her ultimate favor syl a little bit over sylvia, i understand that syl is meant to be stronger offensively than sylvia, but it seemed like the points were more valuable to spend for her overall. Because you emphasized that they are intended to show one of her personalities growing stronger, i think they should be slightly less important for syl, or slightly more valuable for sylvia, to show a proper balance and sylvia's slow recognition that she can stand on her own two feet. (sorry if my opinion is uncalled for, but the numbers seem to favor syl a little, but that might just be me, either way, this is great and i would definitaly get her on release day)

as for a skin idea, kind of in reference to whoever mentioned maokai, what if she had a 'jungle' skin. instead of wearing a white dress, it's leaves and/or moss, syl could attack with small vine like whips instead of her claws, just a thought. also, her spell effects could have additional leaves strewn into them, just as a little touch.
