Third, I was experiencing the same frustration as you are with the Artillery Squad. Nothing I changed seemed to improve the numbers from being close to each other in at least two categories. I thought it was me and my lack of experience. If you are puzzled too, then I feel a little less inept.

I really like having that squad in there but if it's broken, would you just say screw it and keep it in anyway or design another squad as the fifth? If the latter, which squad type?
