Went from 5 star to 1 star. You spend all your time gaining power but the higher your power level is the harder it is to find active teammates, so all your time goes into finding a new team. What they also don't tell you is that if you switch teams, you will start continuously at the beginning again. Meaning I paid for the extra rewards bundle but since I keep having teammates leaving or going afk for days, I'm stuck continuously at level 1 of the event, not progressing or getting rewards.
