The Kotaku guy had his head in the clouds. Look at this sentence in the third paragraph:
I expected amazing new environments, crazy new plot lines, whole new cities to see and slaughter.
No wonder he's disappointed: he expected an entire [censored] expansion, with a focus on new areas to explore and cities to play around in. Like Shivering Isles. Several other people have shared this sentiment on this board as well. I haven't a [censored] clue where they're coming from. I only found out that they were doing this DLC a week or so ago, and in the first five minutes of watching interviews and reading articles it was clear that wasn't going to be the case. That the main reason to buy the DLC is VL form, and Werewolf perk trees, and a new weapon class, along with a new MQ and maybe an area or two you'll get to run around in. That the value is in these intangibles, rather than in new locales and NPCs and raw gameplay hours.
I'm also not sure what to make of his complaint that you can't use potions or spells in VL form. Err...isn't the whole point that it's a new, Werewolf-style form?
