PSA: Balanced != Fun to play against

There have been some recent changes to Azir, Veigar, and Kassadin that I feel indicate some confusion between these things. Balance is when a champion wins half their games, not when they are fun to play against. All three of these champions have been nerfed on account of lack of fun when playing against them in the name of balance. This is an error. You can have an absolutely unfun champion to play against and yet have them be balanced. You can have the opposite as well.

Azir was a lane bully and shouldn't have been so he was nerfed. Since Azir is a high skillcap champion, I'd say that it would be healthier for him to be slightly underpowered by having a 44-48% win rate. Which he had the upper end of.

Veigar was oppressive once you mastered his stun and so was nerfed. Veigar's win rate was already below 50%.

Kassadin was oppressive if he got ahead so he was kneecapped. Kassadin's win rate was already below 50%.

When people wanted nerfs to these champions, many claimed they were overpowered. But there's a difference between OP and toxic. Was Veigar's E toxic? Yes. Is Azir a bizarre lane bully? Yes. Does Kassadin snowball a bit too easily once he gets going? Yeah. All of them needed changes, but none of them needed the categorical nerfs they received. Is it any surprise then that when they did get nerfed without compensation (Veigar got compensation, but as many predicted, it actually had no impact) that their win rates plummeted?

All three were underpowered and yet were given categorical nerfs to who they were. Again, they all needed changes. Azir needed his power shifted later into the game (As an Azir main, personally I'd vote low range on W at low levels, high cooldown on Q at low levels, revert Q damage nerf, and raise ratio on soldier damage). Veigar needed his power shifted out of Event Horizon. Kassadin needed, well, something (not a Kassadin player, so I can't properly comment here); perhaps a damage buff somewhere.

Please stop calling for nerfs to champions that are already losing most games. Just because you don't like facing someone doesn't mean they're too good overall. They might be too good at one aspect, so redistributing power through their skills might be in order. Azir shouldn't be a lane bully. Veigar shouldn't be able to 100-0 with impunity. Kassadin shouldn't be able to stay ahead so easily. But yet despite their problems, none of them won most games. Certain things needed nerfs, but other aspects needed buffs.

Again: is it really any surprise that when you categorically nerf three champions that were already overall underpowered that they will be relegated to the trash heap?

UPDATE: It seems that I've been unclear about a couple things. I'm merely defining balance as having a 50% win rate. I'm not saying that non-toxic champions should all be aimed at perfect balance though. I'm an Azir main, so I'm well aware of how oppressive Azir mains are. We're nowhere near where average Azir players are and given that he has such a high skill cap, this gives us a major advantage in-lane. To those that are thinking that I didn't think Azir was too powerful, you are mistaken. Upon seeing Riot's changes to him, I gave my own suggestions basically saying "I see what you're trying to do and your heart is in the right place, but do this instead because the nerfs you applied made him hardly less a lane bully but did make winding up much harder." In normals, my win rate with him was about 70%. Now, where that means the average Azir player ought to be, I'm not sure, but as I said above, it's probably best to be 44-48%, meaning average players usually lose, but advanced players don't just roflstomp everyone in their path.

What I think should have happened to Azir was first a nerf to his early game in a way that would strike at Azir mains while leaving average players less hurt. The changes that actually happened smashed average users and frustrated mains. In other words, the bottom dropped out from under normal users, but the skill ceiling really didn't drop that much.

What I'm trying to say is that categorical nerfs to champions that are already losing most games is not the way to go about things.

1. If it's because they're a high skill cap champion, you need to go to those that main it and ask "what separates you from other champion X players and how can we reduce the difference?" This is what should have happened with Azir. Instead, he got nerfed categorically in a way that didn't actually remove his ability to lane bully for those that know how to use him.
2. If a champion has a toxic ability, that doesn't mean they need a nerf, it means they need power redistributed from that toxic ability elsewhere, provided that their win rate is not too high to begin with. This is what should have happened to Veigar and it's what Riot tried to do, so I applaud the effort, but I feel like they should have known better than to implement the change as they did.
3. Only champions with rates over 50% should actually receive proper nerfs. Azir, Veigar, and Kassadin did not. They all needed changes, but straight nerfs were not what should have happened.
