The way I see it, the biggest problem with fighting NPC wars is that there’s simply no way that anyone can have coded into the system all the subtle variables and butterfly effect that occur when all sides are actual players. I recall hearing that one the the major nullsec alliance wars was won/lost largely down to someone not paying the rent on a small structure. You’re never going to get those sort of faux pas coded into AI characters. Thus players are really just pushing for one or other pre-decided outcomes rather than the wide array that humans are capable of.
