Riot I think the League is in desperate need of a shaman champion

Just imagine use all 4 elements water, earth, fire, and air against your enemies but also fuse them together to make awesome new spells like in Avatar or in World of Warcraft. A champion that can use his spells together to make new ones would be insanely awesome and fun to play. You want a escape for your team? Just combine your water and fire spell to make a cloud of steam. Want some aoe damage in a upcoming teamfight? Why not make a volcano by mixing fire and earth. Want some nice cc. Why not combine your water and air to make a ice cone to freeze enemies or even make a mud puddle by mixing water and earth to slow them down. Since this champion technically doesn't have a ultimate like champs like why not make his spell fusing power part of his passive like every 90 secs or so he can make a new spell combo. Just my thoughts on what would be a cool champion to have in league. Also was thinking of the champion not being human like sort of a spirit like because I think just more diversity in terms of champion appearance is always nice to have.
