29.03.2022 edit: they still didn't fix the matchmaking system, in fact it got even worse in certain game modes like 2vs2 and events. Fighting in 2vs2 against opponents with 2-6 arenas higher, while your teammate is usually someone 0-3 arenas lower than you, is currently a standard in 2vs2. In events it's even worse. Now also pretty much every opponent has overleveled cards. It used to be such good game with high potential, but greed is undeniably the killer of creativity among developers.
