what if there was two new walls added for village and kingdome made of stone and steel
thay them selfs have a sheild it repairs on a timer if not damaged in 24 hours it starts repairing slowly at first but longer its undamaged faster it repairs
there can be things attched to wall to provide boost (repair timer speed, bigger sheild,ect)
only active when complete (must be enclosed or non functional)
is seperate from claim sheilds (you can take down the auth , charter and sheild but to fully distroy requires more effort type of thing)
one per village one per kingdome (kingdome capitol will have two making it the toughest target)
mostly so bigger sieges will take more time
right now it takes time but with planing and setup the acual atk is short lived (comparaed to planing (3 months planing one day to carry out)) so if it can be prolonged more thrill imo
just a poorly thought out idea might not be needed or have issues lol
