7 sitters in war would not be a big issue that make its way to forum, if it's not CR who doing it, right? ^^. I know some kingdoms encountered this during holiday season like xmas or new year. There's something called life and family too.
Is GF expecting CR not to set sitter so they can win the war "easily" thinking this is the age off for CR? What's wrong with "a kingdom" using a provided in-game feature to win?
