It was hard to get opposite unit stats if you are not familiar with the game. Basically, you needed to do a lot of operations: go to the "units shop", read about some character and assume that the opponent forces have the same properties. From now, you can just right-click it to get full info like in other strategies. The thing, that we had to do long time ago. It is especially useful when there are many mana orbs and crystals on the map. The actual amount of mana in them is a random value, and there was no way to get exact numbers except to pick them up. Thus, every player can plan his tactics even more deeply.
