Edited from earlier review: Arena and Grand Arena are immpossible without spending VAST ammounts of RL cash. When trying to match teams to play against, it only shows teams 2-4 times your power level (after you reach a certain ranking) trying to force you to pay to level your team or do without the arena coin to upgrade or add new heroes. It's a joke how there's NO filtering to only match teams more in your reach to compete against, no matter how many times you hit refresh for new choices.
