Why would you give Xin these changes?
I understand that Xin was not in the greatest place but he was by no means unplayable. Any weakness xin has is not based on his numbers, it's how he is designed. No matter what you do as xin, you will end up using your E and W and Q on the exact same target ( whatever carry is doing the best )
If you have the damage, they will get slaughtered and you have done your job. If you can't, you literally do not do anything.
FFS, stop buffing his numbers. Rework him into something useful other than just another sticky faceroll champ that either sucks or makes the game unfun. Sick of watching this guy go back and forth.
