Riot, please do not ship this huge Xayah nerf
I understand that Xayah may be a bit strong (though I don't agree personally) and nerfs may be needed, but this nerf is quite excessive.
Not only is the total CD gone up for her W, it's at all ranks which will definitely hurt her late game as well. If anything, you should really nerf the damage or the cooldown on her E since you should definitely punished a mistimed E, rather than her W.
