Blackwing Descent is one of the three choices for tier 11 raiding in Cataclysm.  It contains 6 bosses, culminating in a fight against the recently raised undead version of Nefarian.  Its difficulty is comparable to the other raids in the tier, Bastion of Twilight and Throne of the Four Winds.  You can expect to find the early bosses in all three raids to be easier than the later bosses, so it’s normal to jump between raids during the early gearing and progression.
