Like you, I would really like to nail down some solid builds. Yet, I would recommend waiting on this discussion. BWW3 is bringing lots of changes to the professions. I have heard that every profession has had something changed. The Thief has had a serious overhaul, but the Engineer has only had a few minor tweaks. The BWE3 will test the new changes.
So right now, BWE2 data is really obsolete (and we don't have the BWE 3 data to know everything that's been changed). That leaves us waiting and waiting and waiting....
