"2 - I've played nearly 40 turns and no other faction has attacked me yet. Playing as the English and have secured all the available rebel provinces, yet Scotland and France are happy to move their troops along my border without actually crossing it. In MTW1 you were lucky to not get attacked from your allies after a few turns, let alone your enemies."

Are you playing on easy? I'm playing english and only on medium/medium, within my first 40 turns Scots attacked York, France attacked Rennes and Denmark attacked Bruges.
