I agree, but maybe just once a day. A once a week limit is a bit extreme.
Then again you could jsut keep it and not reinforce it and demolish everything in it...

Once a guild has everyone with full citys how are you supposed to overwhelm your opponent?

They have also said in the age 2 of evony that there will be NPC quests or things to do along those lines..

I would rather them get rid of inactive players.
