its not a smurf lol its rank decay. Ive literally decayed, play 1 game and go back to ESEA and then come back sometime later with a friend or something random and get my rank back, but its decayed again.
It expires tomorrow, all my previous coins I bought one day late so the pattern stays. Are you enjoying this operation so far? I wish there isn't that much of casual mode missions, I hate it the most personally.
