Personally, I don't have much of a problem with them being weak. Isn't it supposed to be a tutorial war you can even skip?
I managed to get them to attack properly without making it -that- much harder, it was meant to be easy but it was still a bug so I had to try fixing it, unfortunately in so doing I found another more pressing bug which I am trying to figure out but might need help with from someone who knows a little more about Ruby code than I do. Still trying to fix this old game up a bit!
