I am suggesting the following for tying war decs to citadels after CCP Fozzie at Fanfest said that they were going to tie war decs into structures.
I have suggested that there be a CONCORD agent in a defined citadel, which will allow the entity to declare more than 4 war decs, the agent will also give intel on location and activity of the targets if you go to speak to him in the citadel, and I would suggest that the cost to war dec major entities be reduced because of this.
The war decs will be tied to that agent in the citadel, should the citadel be destroyed then all the linked war decs will end apart from the four last ones applied and it will take a couple of days for an agent to come to a replacement citadel. So the citadel with the CONCORD agent is a meaningful strategic objective.
Does that explain it?
