So many people have made custom skins for other champions which turn out amazing, Lux has a ultimate skin but everyone who knows that they main a champ it gets boring after months, or even years. 
Instead of giving champs who already have skins more and more often, give a champ a new skin who you barely even notice.
This is my opinion.
Stars Shaper1 votesYou know Lux players aren't the only1 waiting for a skin and she already has plenty to choose from?
PeachyBlush1 votesI already know that, especially Illio and Aurelion Sol' need one.
PeachyBubbleStar1 votescough Taliyah too (even tho she's getting SSG)
Final Spark Lux1 votesI feel like there is a heavy undertone of sarcasm here, but I'm willing to ignore it completely if it means we're discussing Lux getting new skins :D
