I dont know if this as ever been asked before but wouldnt it make more sense for dolyaks of one color not to be seen in the map by players of different colors, this makes it too easy for a larger group to overtake a map from a much smaller group since they can cut the supply routes without much effort and if they were not visible in the map by enemies you could raise the reward for killing one and at the same time provide better chances for smaller groups.
Being lazy takes pratice
