I like the humor in D:OS, but sometimes it can be a little too goofy. With more focus on seriousness, I'm expecting more dark humor, and more situational humor that isn't like "Oh, haha, I'm talking well!" but is born out of the conflict of origins and interests and the like. And with way more writers, I imagine there will be a lot more internal dialog about what's actually funny, so even if the humor's tone is the same, I do think it'll be better.
