Allthough I agree in some of the concerns voiced here. I believe we should take it easy, first of all, this isnt a 5-25min multiplayer game like starcraft 2. This is a persistent world where your main base cant be destroyed as I understand it.
So yes Orcs may be somewhat stronger in the beginning, but not like 20% stronger overall. And thats just taking the mecanic of the game into account. Never met many players who play equally well in the same game at all time. Chances are that enviroment, luck alliances etc effects every outcome. So essentially its about hoard all the advantages you can, and utilise them to their fullest extent.
This ofcourse means, that All have to bow to my santa clad & marylin Monroe Orc look alikes soon
