Doesnt justify it's presence, it felt like a rehash of the main story with a new location. The frozen area is gorgeous for what it's worth and I was able to get better weapons because of the expansion. The level requirements are a joke, if a preceding mission has a level requirement of 40 why jump all the way to 50. But going under-leveled for the final mission didn't really feel as difficult as I had thought. The shield weaver outfit never goes wrong even if you are 10 levels below the requirement for the mission.
