[ANNOUNCEMENT] Heroes 3: World Tournament - an add-on for tournament games.

I was sure that it was done this way because it is difficult to implement mana drain programmatically.

You shouldn't be so harsh. The point is that when mana is very important, you can fight on quick battles without losing it, but there will often be some losses. That is, variability has been added so that the player can decide for himself what is more valuable: to possibly take damage or lose mana.

This is just ridiculous. We remove the quick kill ability from Gorgons, and we get damage loss because the bot will fight worse. But you can fight better, but with the possibility of taking damage from an ability. Variability, right?
