Players that purchased premium pass have to grind 15,523 rounds each day on average to attain level 175, starting at level 1.The thing you've said is total nonsense. Players said fix it, not ruin it even more in an opposite way. In order to get 175 level you have to grind 24 rounds per day.
This is only fair, as developers have spent their time creating cosmetics and skins + the journey overall.
True loyal fanbase either support this game financially, or by dedicating their time playing this game.
There is some truth in what @Lantea said, that it creates an incentitive to play this game, if you are able to attaint the Ciri skin, by playing 10,000 games with her, as an alternative acquisition method. Given that next journey will bring several other skins, which equally will take time to acquire, this makes it a reasonable compromise.
There is also a high possibility that these skins will be on sale, depending on how the journey progresses, and the number of people who dont compleate it in time.
