TL;DR: It sucks (always has been, but even worse now) to be f2p in 2025.
Now, you can only rely on those goofy boxes to get Legendaries/Champions, and they nerfed the boxes as well.
Dudes, I only get a 5* box in a whole year (it gave me a rare book of books), and now you’re telling me the chance is even lower? How am I supposed to level the Champions now?
