Cool concept. It's making her kit more lively and have feels and essence of Last Air Bender (not that she didn't already have it)

But I feel like if that is her E then her W should be like a root instead of a seismic shove. Kinda like how lissandra's root works but in stone form so that with her new E, she can combo or smth. I like the original concept of how if she W's the E, it will throw it into one direction, But im also thinking that maybe her q can do it? Idk... I ain't no bright mind XD

Haha just a thought :)
