If you want progress - pay!
I was playing over year this game - engine is made such way that without buying its very hard to make progress... For example in single war you have to win 900-2000 coins, in few minutes you always!!! Lose 1300-1500. Even if first attaker got only 400-500 next in 1h will get 800-1500!. I am also playing C.O.C and this game is playable without buying...this not.
