Even in chess, White always moves first...
Relative balance can be achieved. THE MAIN SKILL OF THIS Castle CANNOT possibly ruin the balance already present in the game. IT SHUTS DOWN OPPONENT ABILITIES WITHOUT GIVING A N Y A D V A N T A G E ! ! !

Think about it yourself - without special abilities, Heroes5 will turn into Heroes3 and everything the Nival developers achieved will go to hell! The game will turn into a stupid brawl where quantity is the main thing. That's why I don't play Heroes3 anymore - because 3DO threw in too many overwhelming creatures, especially with the last add-ons, and the game turned into a mindless race for power and numbers! Stupid and uninteresting. No brain work involved.
