I would put it to the community that one of the roles/responsibilities of a Faction Leader is to be a Game Master for their faction - and be part of a team that contributes to an overall story.
Factions offering RP directions need to be able to account for the RP of their enemies as well as their allies. Faction Leaders need to be flexible - and be able to offer a number of possible RP scenarios.
The role of an administrator(s) should be to guide that team:
- Vetoing concepts that are plainly absurd or unable to be accommodated by the overall story.
- Offering qualified support of ideas put forward by the Faction Leaders (ie: ideas that could fit in with the story, with some modification).
