Don't forget the Wit's End changes that pretty much mean the rageblade nerfs aren't going to gut him like everyone thinks.
Rageblade changes will slow him a bit, and will slow Vayne a bit...it'll all but shut down some Varus and Kog builds and will mean that Kayle has literally nothing for early game anymore.
The issue is that they want to elevate him back into pro play (the last pro game I recall him in was pre-removal of AP Yi on AlexIch) and the solo queue players are once again left to suffer for the sake of competitive/pro play. I thought they were learning when they started lowering the damage a bit this season so tanks could be more relevant again, but they're still leaving some pretty ridiculous players high on their thrones while area nerfing entire groups to oblivion with item changes...I get rageblade, but I really don't understand the Wit's End change at all.
It was underused, but a fine niche. I hope they revert it when they realize that adcs should have the old niche version back after the gunblade changes, but I know that's never gonna happen.
