why limit the fun? if I am having fun with the game let me have the freedom to pick my own playstyle. I could play more battles and get less rewards or even play none stop and get no rewards. I will improve my skills instead when I play more battles. I could push the leaderboards and be competitive or burn my ECR and take a break for 4 days. it is right that the ECR is complicated but it offers so much flexibility and so many playstyles that will suits everybody and every situation, some days I play more and some days I play less depending on my mood. With the new energy system there will be only one playstyle and in my opinion it will get boring real quick. just like any mobile game that have an energy system to limit your fun. I hope the team reconsider this move. I am afraid this would be the case of " you don't know what you've got until you lose it" rip ECR system. I really hope I am wrong about this tho
