For the sake of argument...
If this feature were going to be added to AH, I'd think that rather than overall "rank" being the determining factor to enter the HQ War Room, it would rather be the number of successful Missions initiated and conducted by a player per Tour.
As examples, from my limited experience with the Bishies, Ghi and Thunderegg seem to plan and conduct successful missions. And there may very well be others that I do not know about because of the hours I'm on. They have low, 3 digit ranks, and they probably could work to get ranked below 100, and maybe they have been in the past. Nevertheless, if X number of successful missions per Tour were the basis of entering the HQ for stategy discussion, then "rank" high or low would not be a factor.
Just an idea.
