I know the skins have been around for two weeks now but I only got a chance to look them recently. Have you guys considered removing Syndra's voice filter for the skin?
In my opinion, the filter doesn't fit at all with the skin. She has this dark sorceress sort of thing going on with her voice and it just seems out of place on the skin. I think it might help pull the skin together for her.
Just my two cents. Feel free to agree/disagree.
