I used to rate it 5 stars because i thought it would be a perfect strategy game but,yeah its perfect strategy game but its hard to get defences cards and hero cards and i used to log in my account on facebook to save it and i was in chapter 13 and i uninstall this game then download it again and log in my facebook account when I log in it I'm shock because i was in the chapter 8 when i log in my fb account.this game need to be update on log in and log out system.sucks
