so we've played out Clash at Kingsroad 3 times i am always Lannister as they are my favorite house and my friend is always Stark and it seems like i cannot get a win at all, my friend forms a triangle with mage mormont at the northern crossing, and uses the archers and Karstark to plug in the southern crossing, i throw myself at him with both Marband and Kevan but the Archers on the hill and his friends are constantly thinning out my ranks while Karstark acts like plug stopping me from ever pushing foward to the second objective.
what am i doing wrong?
