I may be making huge jumps to a conclusion that doesn't follow, but perhaps that change in focus from team-based, realm-centric conflict toward personal political power struggles is part of the reason for the declining player base? I can't be the only player that prefers the "old school" style of team play.
I think it can be possible. After all, when nobles in high positions quarrel between them to the point of paralyzing the entire realm, it's hard for nobles or less important Lords to have a glimpse of what happens, besides perhaps sporadic huge public discussions. And for a newcomer it's not exactly easy nor stimulating to see people not doing anything besides arguing to death on pointless things, especially when half of it is done behind closed doors.
