The eternal question: which heroes are better, mages or warriors?

Magic is a useful thing, but it's not reliable. It can fail at the most crucial moment, especially if the game has dragged on, and everyone is laden with artifacts like a Christmas tree. There are a thousand nuances (that's why we love this game:D), but a warrior should have a numerical advantage over a mage. This is an elementary law of logic (imagine what one Susabrod with 1 black dragon and Armageddon can do)...
By the way, this is not an indicator of advantage, because if at least one spell in the mage's chain of planned spells is reflected, the whole chain collapses.
