I already use the berm and moat, you're right, it works great against anything that doesn't fly, I was content with the raids until flying stuff started coming. As far as the draw bridge goes, if you leave a little gap using roof thatch panels over the moat the mobs can't path over it but you can still run back and forth, like having a ladder just off the ground, works pretty well.

I just use a single 4m core wood beam. I can walk over it but the mobs can't. I build floors attached to the single beam to take a cart over and remove them when I'm done.
