On a random note, Addam Marbrand (Warrior of Ashenmark) is my favorite commander in the core game. He's not flashy like some of the others but he's just a solid and dependable commander who always seems to play an important role in my strategies. Though of course you use him in almost all of the battles in the core game.
Just last night it was his cavalry wing that flanked the Starks and captured Catelyn Stark in sceanrio five, and also killed the last Stark Unit to give me the 5 VP's I needed to activate the instant win condition. Go go House Marbrand!
I couldn't agree more! In scenario 1 it was Marbrand's cavalry which raced across the river on the final turn to ****** the objective I needed for a Lannister victory - to the complete chagrine of my dumbfounded opponents - in scenario 2, it was Marbrand's unit that managed to destroy the Stark cavalry holding one of the fords, and then tie up Rickard Karstark's 'deathstar' unit in the dying turns of the battle, and in scenario three it was Marbrand's cavalry that routed the last Kennelmaster's unit, thus securing a Lannister instant victory.
All in all, considering I have only played these three scenarios, he would seem to be the dog's proverbials.
