I play axie and I know those guilds and what kind of "players" they bring... The issue I see is that they dont bring players they bring "schoolarships". The main difference between those is that schoolarships only invest once or when its absolutely necesary. After that inicial investment they just extract money from the game. They work the same as bots. When you make it really cheap for them to enter then is a no brainer for them.
Of course you can argue that those players are not actually bots and might like the game and reinvest with their own accounts. Well thats true but unlikely (on a grand scale). Or at least I think there are better ways to atract those users. You can do promotions for big youtubers and that kind of stuff and will probably have the same results.
I have no doubt that the active daily users will increase but they wont bring money into the ecosystem wich is what every crypto game needs.
Those are my main concerns with this, I saw it happend on other crypto games, even in axie. In fact those guilds are not investing this money in axie because axie its not what it used to be in terms of profit.
