I see a few bloggers saying that they are not "ready for raiding" yet.
My raid team is the guild's second team, and we have only just started raiding (two raids so far, Tol Barad boss and Magmaw down) but what we have been doing for a couple of weeks is farming trash in Bastion of Twilight. The trash is easy once you learn the pulls and have a couple of reliable cc-ers, and there is a very high chance of getting a BoE epic - we normally get one epic per run, but sometimes we've had two. We've had a couple of tanking swords, a couple of rogue ranged weapons and a druid tanking helm so far.
The best thing is that they are BoE - if no one in your raid wants them, stick them on the AH and use the money to buy an epic you do need!
Maybe something to consider if your guild is still gearing up for raiding.
