It take too much time to get a decent power level if you don't spend money. The event reward system is broken after spending many hours collecting it reports an error when trying to redeem. After the event the entire collected rewards disappear and any rewards can't be claimed Even after spending money to buy initial pack to get ahead in game. It's very repetitive with too much grind to get the new power up.The division making system is also terrible all open divisons report "too many requests"
