(Sorry for my english)
I started playing CR 2 weeks ago and i’m in arena 11. I’ve progressing at the game without spending money and my king tower is lvl 8 with some of my cards being lvl 8, while most of them are lvl 7 or below (2 or 3 lvl 9). The “problem” i’m facing is that most players I encounter have a KT lvl 9 ar even 10, with most of their cards being lvl 9/10 or even 12. So my first thought is that they paid for all those lvls. But i don’t know if maybe i’m missing something and i’m not leveling as fast as I should. (Or maybe they are so bad they are stuck in elo xd)
