As you might have noticed we got ourselves another BH earlier this week. Now I'm situated on an all but dead realm, but you really ought to get out there and start pugging FL if you haven't done so before.
By shredding the bosses you ought to be able to take them on rather than being satisfied with a trash pugging run. Semi-abyssmal dps ought to be enough to take out 4/7 bosses.
With decently competent healers and tanks Belth and Shan should be quick work. Dps still needs to be able to steer Ryl, and obviosuly everyone has to be able to rotate shards on Bal.
Still, give it a shot.
