Other than a title and achievement, what benefits come from being declared Emporer in Cyrodiil? I'm not knowledgeable at all on the finer mechanics of Emperor-ship, but I do have the following suggestion:
As currently, the #1 position is given to the emperor, but I suggest positions 2 - 6 should be made generals. The generals' positions should be visible to all on the Cyrodiil map, but obviously only to players of the faction they represent. Generals can also be given a unique skill line, with actives & passives supporting their roles as leaders. Generals, in turn, can view the location of all the group Leaders of groups in their faction currently active in Cyrodiil.
