Riot why are you nerfing AP Xin?
The nerf to his W's ap ratio that is currently on the pbe will completely gut the ap Xin build, and I can't for the life of me understand why you are doing this. The ap Build is very fun but not so dominant that it needs to be beefed.
If you are only trying to nerf ad Xin then hit the base heal which would hurt him, but still allow ap Xin to continue existing. All the current change will do is nullify ap Xin's existence while doing nothing to the power of ad Xin who gets so little ap usually that a nerf to the base heal is the only thing that would effect him.
Edit: Why the downvote? I am complaining about them gutting an off-build, do you want your favorite champion's off build being gutted?
