I think AJ was only good for information during TBC, nowadays it's utter crap. I can't even fathom why there are people still posting on the forums there, since there hasn't been any decent discussion or moderation there for ages. It's pretty sad, I wish there was a good PvP site with guides and so on.
Yea I haven't been to AJ since early WotLK. It's just garbage now.
