Thanks for all of the response's, that went really quick! :O
I've gotten some enlightenment on the khergit but i suppose, that i pref. the old khergit army style, from vanila troops, where they are pretty much all mounted, which causes way more flexability.
I never said that the nords where weak however. I dont like playing them, because i enjoy good range troops, and the nords A4 bog. just does not really hit the spot, so to speak. Here, i tend to do a 50/50 nord/vaegir or rhodok/vaegir army combo, with heavy badasses in the front, and incredible vaegir archers to scatter the enemy before they even reach you.
