So, it's about 1715 in my first MC campaign; I'm at war with just the Mughals and slowly making my way north. As I progress nearly all my forces move further north. I haven't seen any reason to garrison souther India because Mysore is a good ally and the Dutch are just holed up in Ceylon. Neither appear to be doing much.
But it does leave my southern provinces undefended; have you ever seen the Dutch or Mysore attack the MC? Or perhaps a fleet from another country land an invading army?
Should I bother leaving an army in the south?
