This game thought it was great at first till you get to chapter 4 where it says I need all my units to be Elite 1 Lvl 50 but I still lose, it doesn't matter if my units are all Elite 2 Lvl 25 I still can't win its as if the game became PAY TO WIN at chapter 4 I needed 5 star or higher to continue and the drop rates are FULL OF RUBBISH I wasted over 200 draws and only got One 6 star, Three 5 star and a whole lot of RUBBISH 3 and 4 stars. I've played for almost 1 year and still this happens.
