Man it's a blizzard cinematic. How climatic would it have been had she just gone in there, full banshee mode and remove the helm of damnation all within a minute? Yes on paper what you're saying makes more sense, but com'on man. We all know that would make for one shitty cinematic and everyone would be ripping their hair out claiming it's the worst cinematic ever produced by blizzard. There has to be some suspense.
