I wont spoil anything but LoTSB has finally met his match !! The Citadel DLC is a thousand times better in regards of missions, fun, gameplay and most importantly POST DLC content !! Seriously Lair stands no chance with his small area that you could access after the DLC (the control room) because Citadel has so much more after the DLC is done.
Hopefully anyone sees now that BW can still do DLCs after the "mediocre" Omega DLC.
