By Old raiding guilds I mean Raids for MC, Onyxia, BWL, and Naxx, I want to get all Teir sets before I work on Kara, I know armor in BC is better then T2, But I'm an armor collector.
Doubtful, although on my server on horde (Stormrage-EU) there is a pick up group to Naxx/MC every week. Didn't go the Naxx one but I know they got some bosses down.
