Glad you’re enjoying the game! In fact the coming update will include some AI improvements – including better decision making of when to go on the offense and when to stay on the defense. Goblins use quite a defensive approach to battle, so they most benefit from this, but all intelligent opponents factor this into their behavior now. There’s a lot more I want to do in terms of formation and tactics, like the good examples you’ve given, but it will have to wait a bit longer :)
