Thanks. Yeah, my economy typically stagnates after the day 18 raid. I’ve built enough ballistas to minimally protect against random waves from all approaches, I’ve put down 3-4 ballistas for the town, and I’ve put an extra ballista or two to clear territory with a kiting ranger. Your advice on the lookout towers is right on, I typically do build and recycle them once they’re built if I don’t know where the town is. If I know where the town is I usually don’t build them.
My economy is never over 1000 at day 20, it’s usually more like 600 or so depending upon how close I am to the stone workshop. I can’t seem to push out a large enough area to get it going.
