Whats the point of even trying to take back a gym when our opponents can just heal up while were trying to beat them, its also annoying when youre literally just a few hits away from taking out one opponent just for time to run out and have to do it all over again with your opponents having full HP and you having the same amount of HP you had at the end of the battle. This is way too difficult than it needs to be, all youd have do is make battles turn based like the game.
