New Xayah, Volibear and Cassiopeia skins

So it's been awhile since I've been on here but I've noticed Riot has been doing some neat reworks plus adding skins and such for champs and what I've been waiting for is new skins for Voli and cass. Now I may be jumping the gun on the voli, especially since I know riot is planning to rework him a bit so perhaps theres a skin coming for him, but what cass? I love to see my main finally get a new skin, as she was the second I got M7, the first being Xayah. Which brings me to the best adc in game <3 You allowed a drop for rakan skin, but not one for xayah..? Kinda spat in the faces if xayah mains, like me, whom like to play with rakan and match skins, but cant because you dropped an exclusive skin for him and not her? Why not drop a skin similar to it for her and make a knock off, for the sake of keeping them even and matching.
