The point of this blog was never to justify my decisions, more to be a resource for users. If people want to discuss my personal ratings for individual champions: they are free to do so in the comments.

As for Kayle - what you describe is the definition of acceptable. If she's only subpar because her wings need reanimating, then Riot could--in theory--just update that as they did with Cassiopeia's tail. I think she needs a full relaunch because her kit and design are bland, but her current model is definitely acceptable.
