Your right as that would not be nice.. I think there needs to be a cost for declaring war and a war running cost on a daily basis. The cost should depend on the ratio of active members over the last 30 days as there are alot of zombie guilds about (150 members but only a couple active) between the guilds.
So if the base fee per day is (pick a number out of the air) 1,000,000. If the declaring guild has twice as many active members the fee doubles and if they have half it halves.
