Doc's campaign gives the ai clans a more advanced starting point on the tech tree, and better units to start with. He has also adjusted the preferences for what kind of troops the ai will train, and he initially lowered the invasion thresholds to make the ai more aggressive. However, I think they are set back up because they were so low that the ai clans decimated themselves attacking each other. I'm not sure if he adjusted the ai's building preferences, but I know he wanted to.
