It's not that thread:
That thread is who got each of the 4 bosses down (and has a point system). This is who cleared NiM EC in under 2hr. People have asked the Astral guy to add a 5th heading (making the title a "boss") but he's turned down the idea - I suspect that maintaining the thread is work enough and having to keep it up to date in regards to the title "the Warstalker" is too time consuming (I mean the guy does have a life outside SWTOR).
This is the only Progression thread that I am currently maintaining, and as such I can dedicate a fair amount of time to maintaining it.
