dear warlords,
Let's try to imagine one situation. you have 1 heavy cavalry and you have to attack either one of two cities (wall 0). in first one there is 1 wolf rider, in the second one is heavy cavalry just like yours. Which city would you attack to have bigger chances to win?
Correct answer is:
second city.
When you attack it you have 50% chanse to win, it is simple, isn't it?
When you attack first city (with wolf rider) you have 49% chance to win!
chance (of wolf rider) to win = 16%(ambush works) + 18%(ambush don't work, but you loose 1 heart) + 17% (ambush don't work you loose 0 hearts) = 51% !!!!!!!
I hope it will help you in future battles,
