dogs and knights as new troops
dogs-enemy troops
3-1 infantry
6-1 calvary
4-1 archer
10-1 catapult
and if knights are added
15-1 knight (because knights are extremely well armored and armed)
The knight would be very strong against dogs and infantry, pretty strong against calvary, weak against archers, and moderately strong against catapults... this would also give archers a main role on the battlefield...
and my ratios would be based on a new game with 0 upgrades so when the tech of atk and defense are leveled up the deaths would drop... and the dogs would be the second best prestige-resource ratio behind archers and knights would cost a little less than calvary but would eat more crop
