Orcs vs. Humans

Only Subjugation can stop the powerful stack of the Orcs' relentless war machine. But even then, the Chieftains and Daughters can finish off the remaining units while the Cyclops will be significantly slowed down due to the Knight's low Defense skill (penalty on Subjugation).

That's exactly what I'm saying – it's enough to quickly use Subjugation on the Cyclops, and then the Knights will quickly eliminate the Shamans and Chieftains. After that, they can deal with the Cyclops. It's not even certain that the Cyclops will get a turn before the hero's turn, let alone several turns. And that once again speaks in favor of Darkness against Orcs. :) And if Vampirism is also present, that's even better.
P.S. I watched the replay – it's just another inconclusive and unconvincing match. If Mdance had provided a proper replay with decent players (and he was offered to play), I think many new nuances would have emerged that should be discussed.
