Have played it multiple times now, being that the gargant king becomes a hero allowing him to take a command trait and artifact, it turns him into an absolute menace. Give him +1 weapon damage and battle brew and watch him maul anything on the field. Although, since it has no point cost you will have people cry about it, so I just say 100 points and make the whole thing 1000 points even. Great battalion 10/10
To add to this review, keep in mind always how characterful and fun giants are. They can be amazing and terrible rolled up into one big lumbering drunk dumby. This usually results in very fun stories that create conversation pieces for years to come in your gaming group. Take for instance one of my giants, who fell on the skaven general and killed him winning me the game. You cant write this stuff folks, its just pure savage fun.
