The thing Im afraid of is the economy of the Orcs. Sounds like that they are able to control the first part of the game because they are nomads and hunters. If they are able to gather some offensive tropper faster than Elfs and humans in the beginning, will a fast attack before the Elfs and human get the possibility to build defences not make the orc's a overpowered race?
It would be just like in Starcraft 2 with the zerg 6 pooling. Yes the zerg lags economy, but is able to build 4 zerglings that cant wipe out anyone, unless they are able to wall off.
Now I havent played Dawn of fantasy yet, but i hope that will change soon. I think I have to see thing with my own eyes.
