The EU celarus campaign (the new 14 day one) seems little more than an emperor farm, with little opposition to the central ring of keep being taken between AD and EP.
Further to this the emperors retire just a couple of hours after getting the title (and passives)and process swings to the other side. There is collusion between the sides, spoken openly in zone chat, and agreement between the prospective emperors to be.
The campaign is a corrupt farce, merely being used to propagate cheap emperors.
