Are these planned? If not, I want to argue for them --- I think this belongs in the fora, as it's kind of a stylistic choice. Anyway, I think there are two good reasons to add them:
1. I think it'll make it easier to engage with the game emotionally, and help to develop the "post-disaster" vibe that I think Arcen is going for. I mean, after a disaster of this scale surely some people are going to wind up trying to survive in a more aggressive way than standing around next to an Illari stone and banding together in peace and brotherly love? I think seeing human bosses --- and hopefully human lieutenants and overlords --- would make the situation more interesting. I don't feel especially angry about monsters hoarding resources and oppressing the land --- after all, that's what monsters do. How the hell can you get mad at an amoeba? And the crippled dragon is kinda pitiable. Whereas a human who's lording it over a stronghold full of giant skelebots and crippled dragon, or hoarding some stone, or rampaging across the land demanding resources --- he had a choice, and I can see feeling a lot better about wiping him off the map. Plus, maybe one day, when the game is more developed and has more story, it can force us to sit down and think about the real moral calculus behind killing off a band of the few survivors of your own kind just because of how they've responded to a pretty nasty situation.
2. It is also a cool and interesting thing in these kinds of games to see whether you can beat someone with the same powers and abilities as yourself. If the new AI is going to be able to decide between and use a range of different attack behaviors, surely a human with a variety of different spells is a good way to show it off?
