@Riot The nerfs that feel the worst are the ones that say "their fun is more important than yours"

Nerfs always feel bad, underserved or otherwise, but the worst kind of nerf is the kind that says to players "your fun isn't as important to us as someone else's". This happened to Evelynn Season 2, leaving her intentionally horrible, so bad in fact that she become shorthand for "I'm trolling, dodge", and people were legitimately banned for playing her and doing poorly because it was hard to distinguish a bad Evelynn game from just plain trolling. Evelynn players were abused by the community, and their fun taken from them by riot, because their fun was impacting the fun of others. You didn't see Evelynn every game, and she was never overpowered. But playing against Evelynn was frustrating for new players. So Evenlynn players had their fun taken away.

That's the most extreme example of this happening that I can think of. But it has happened to other champions to lesser degrees.

This is the worst feeling sort of nerf. The sort where a champion who isn't actually too powerful, but the community outcry is. I thought Riot had abandoned this idea, Kalista's existence seems to spit in the face of the idea that a champion who isn't fun has to be kept competitively unviable. So why does it seem like community outcry is still affecting who is nerfed and who isn't? Why do champions who never or almost never even get looked at for competitive play, get nerfed?

I'm just perplexed. Riot why?
