2 Kyle: This is a standard rule that has survived all four tournaments... accept it as a given.
Alan, everything changes eventually... :)
This rule is IMPOSSIBLE to track in the game!
I gave an example with Heroes 1. When the computer attacks with a level 1 hero against centaurs and they die. You will never know if it was a computer player or not! You can't track it, and I can't track it, and no one can track it at all :)
Therefore, it's better to allow it! I would even say that it should be allowed and this point should be removed from the rules!
Sincerely, VDV_forever
