I think it would be great if they add more modes to ladder, like 2vs2 or even touchdown. The mode of the globin queen is very funny the first days, but then is so boring because you see always the same cards, so they should explore new modes to add variety to the game.
Another feature they should fix immediately is the clan war. Most of people don’t play them because the rewards aren’t so good and the system of training days is useful so people don’t interest them.
