no one gets to have good games on them because of the 0.001%
Only if you're assuming a lower average winrate/rank means lower satisfaction.
I think its important to look at why certain players would main certain champions here and I think there is a (decently substantial) number of players who picked Azir specifically because he's the "Pro Player champion" and find satisfaction from being able to play him.
Sure there will be Azir players that just want him to be better in their soloqueue games who will be happy to see the winrate increase but my problem is that those are the players being catered to by these and many other recent changes and it feels like the former are being treated as though they don't exist.
What I want to say is that I think the game should promise you a certain amount of success for fully learning a champion. I don’t think Azir does that. Not that you can’t win on him or have fun, but that it’s typically not worth trying as the payoff isn’t good enough. He’s tuned very low because of pro.
