dear gree,
apparently a lot of android user have started using a bot to kill epic bosses for them allowing them farm a boss every 2.2minutes or so 24/7 (i assume using bluestacks, but maybe theres a phone app aswell)
can you please check through your player logs and remove these units? (should be fairly easy to see who is doing it, just check for people who have killed 1k plus bosses and done it on exact time intervals)
