For those still doubting Elementalist Lux

Back in February, Carrie Keranen, Lux's voice actress, did an AMA on the League subreddit. During said AMA, I had asked her that if offered to reprise her role, would she do it, and she responded that she would love to play Lux again.

Last night, when I was looking through twitter, I came across a tweet from RiotLegendLarry from back in March, one month after her AMA, saying that it was cool to meet Carrie at Riot's office, confirming that she had visited Riot, presumably to do voicework, confirming that a Lux skin was in production.

As for why the skin is Elementalist instead of some other theme, as everyone would see Void Lux coming from a mile away, back in Carrie's AMA, when asked about other roles that she wished she had gotten, she said that she really wanted to be on the Legend of Korra. So by turning Lux into an elementalist, Carrie not only gets to reprise her role as Lux, but also in a roundabout way, she gets to be the Avatar as well.

It all makes sense once you piece things together.
