To everyone stating that Elemantalist Lux is nothing but a bunch of chromas...
...it simply isn't true.
Each form has a unique personality, while still being uniquely Lux. In every form, you still have her old, light hearted, positive mentality slip through in places, but, her personality does change depending on the form shes in.
Light is.......well, Lux (just more mature) Ice is cold and calculating (no pun intended). Fire is hot headed and feisty (again, no pun intended) Magma is head strong and stubborn Nature is optimistic and care free Mystic is quirky and curious Water is smooth and level headed Storm is quick and domineering Air is captivating and active. And finally, Dark is mischievous and seductive.
And lets not mention the MANY different models and particles. I'd say that each form is AT LEAST worth as much as a 1350 skin all on their own, without including the VO (which would actually make each one a Legendary).
Oh, and lets not forget that this skin is the most interactive skin we have EVER had in League. Spirit Guard Udyr has some, but its limited by your gameplay. DJ Sona also is somewhat interactive, but you're limited to only 3 different forms.
Riot has said that the Ultimate skins are a way for them to push their tech and artists to the limit, and with Elementalist Lux, they decided to crank the interactive portion of the Ultimate skin line to 11. You can have this skin reflect who you are in game (though, it could take some time), without having to buy multiple skins in order to show who you are like behind that screen.
This isn't a bundle of chormas, you're buying, this is a very well designed, absolutely epic skin. So to all of you haters out there, I'm sorry you won't get to enjoy what so many other people will.
