I know what you're thinking, another Xayah/Rakan skin idea, but hear me out.
AND HEARTBREAKER KLED.
You heard me right, it would be a Xayah/Kled skin. Xayah ran off with Kled, leaving Rakan heartbroken. They would be 1350 skins, and all the Rakan and Xayah love quotes would be removed (if the 2 champs are in the same game and one or both of them have the skins). Also, Xayah/Rakan's synchronized recall would just be Rakan giving Xayah the cold shoulder. And for Kled, instead of riding Skaarl, he would ride a motorcycle. His ult sound be engines revving up (not the initial fanfare though, as he comes flying past gets changed). Also, the Kled skin would have a special taunt to the Rakan skin: "Whoops, accidentally ran off with your girl! Ain't that a bitch!"
It would be the perfect kind of skin to suite Kled, and it would be a nice change of pace from the lovebird Xayah and Rakan skins.
