Oh I read your explanation. And I understood it. Maybe you aren't understanding me? My point is it shouldn't need to go through uPlay to authenticate it and it doesn't actually need to. Seems they have just decided to do it this way, even for multiplayer offline in system link which is flat out ridiculous. And on that basis I'll not be buying it.
As much as I'd like the new weapons I refuse to be forced to log into a Ubisoft server to use DLC offline on a console for DLC that I've paid for and downloaded via the Microsoft marketplace.
