Love this game, very strategic..although it could use a shop for selling all the tons of extra soldiers, weapons, armor, shields, and special items gotten from the packs. So you could buy more packs hoping to get the items u want...or simply add in a upgrade system so a common item can be upgraded to uncommon. Then uncommon up-gradable to rare and so on. Otherwise currently a player is stuck for days grinding gold to get enough for the best packs. Even then the chance of getting something useful is extremely unlikely.
