Orcs vs. Humans

Could you please tell me where I can find information on the distribution of the main attributes for the Orc? I mean, what is the chance that we will get attack/defense/spell power/knowledge? P.S. Sorry for the off-topic. But I'll still add my two cents: on small maps, the Orc will win if the Knight doesn't find mass evasion. And on large maps, the Human will create cavalry, use light magic with mass buffs and resurrections, or dark magic with mass debuffs and mind control, and berserkers. I don't think the Orc has much to counter that, except maybe a special ability...
