This raid instance is actually farmable. A solid group could clear it within 2 hours so a PUG shouldn't have too much trouble killing a few bosses in there. The first boss is actually really easy and a group with half green equipment could kill him without much trouble. Probably the best way to farm for your skill books. Also a group of 3-5 can actually get better gear from the CC faction. Some of the items are easy to get provided that you do enough of those quests and get your rep up.
