A lot women loves to keep their castle wall heavily guarded to keep us barbarian out, but when we do breach these walls we tend to find out the treasure we coveted  was nothing even close to what we expected. Acquiring this new territory has made life more difficult rather than  simple. The barbarian are at their best when conquering and  remaining  mobile not settling down in a castle that took them time and effort in breaching because now it falls on to you to now protect it.
