I have been doing this for a long time and agree that the medals that drop from each valley are random. My big issue is has anyone else noticed over the last week or so that the number of vallies with no archers or Cav has dropped? At one time I could easly find 5 or 6 vallies to hit a day each being level 9 or 10 but as of late that number is more like 2 or 3.
