Although his blade bends a little too much for my taste, I think Shurrak is a very fun figure. I have enjoyed using his on the first OM and then swarming the enemy with orcs on the second OM. Not only are you using a heavy hitting giant to chop the enemies into little frankenscape parts(well I'm sure that's how some of our modders do it
), but you can also make enemies fall into an orcish bloodbath(by swinging them behind or to the side of Shurrak).
