Long post on AI, short answer:
AI is hard. Really, really hard. And Nowhere Prophet has a system in place I'm pretty happy with. It's not perfect and it needs some tweaks but there's not going to be a major AI rework - simply for lack of time. I'm not an AI expert and building a really really good system (see Eternal for example) is hard. So unless you find someone who's good at this exact problem and willing to put the time in to make a new AI (for free, cause there's not really much in the way of budget either) then I'm willing to look at it.
But from where I currently stand my time - besides some much needed tweaks - is better invested in working on the content than redoing the AI system :)
