I don't mind your system Coca , it needs a bit more work and clarification but its a good base ... as a matter of fact thats how I thought the war system would work.
I think asset destruction should be limited to those windows as well though, even being an old school pvper I won't enjoy having my town attacked for the sole purpose of " we just wanted to destroy your stuff". I also think that upon declaring war upon a tribe if those windows are implemented BOTH tribal areas should be open for asset damage and totem destruction. This I attacked and you must defend stuff is for the birds ... I want to see actual repercussion for arbitraily attacking another tribe.
