Am I doing it wrong? I spent about 800 greens and I only have 4 seven star players... Or maybe because I invested it mostly into giving SA+role+7* to Petersen and my defendre... Dunno lol.
I just do all 3 types and then on the half hour mark, do the first 2 and then all 3 will be back for the next hour. When do you apply green packs to your players?
