Okay, I admit, I DO suck. I just tried the first scenario (Green Tide Rising) of the orc campaing in game Warhammer: Mark of Chaos and I could not make it. My green skinned heroes kept dieing in the final battle and I honestly do not know what I possibly could have done better. I tried my best to keep my lines tight and men fresh, used my cavalry for flanking attacks and made my heroes to boost their troops the best I could - and still, I failed..
Maybe this will get me going.
