According to the update notes on the official website (which actually isn't the best place to check for updates, but it'll do), the last skill update of any kind was in September 2012, which was an Elementalist overhaul. The reason you won't see a lot of posts about builds these days is because the skill set is static and has been for a long time now. I don't do a lot of UW farming but the chamber is certainly doable.
