I'm not sure what the point of camp followers is. If they turn out being useful or interesting then I guess it would be nice to have someone like Sazza.
Like, I get having a blacksmith in the camp. Someone who can produce something of value. I get having pets. I suppose a sage makes some small sense. But if it's just an NPC sitting around saying the same line over and over again...

I don't like any of this binding stuff that's entered the discussion. Truly out in left field, in my opinion.
Just like the Lady Vengeance offered you a team of people to work with between adventures, I think the camp followers present the same idea/opportunity, except more customizable/decision-dependent and interactive. Or in DA:O where helpful sorts could join your camp. I'd like to see a mix of the two with a bit more interactivity and variety in dialogue. Each camp follower can have different skills/means of helping or assisting your team, different banter, different knowledge about the world. For example, Halsin is a knowledgeable and wise Druid who can fight and give advice based on the world. Volo is a storyteller and a bard who can relay your exploits or tell you about his experience with the world (while being a bit flexible with the truth); he's also comic relief. Having these types of followers shouldn't just be for the good route. That's why I brought up the Illithid powers as a means of recycling some content with evil flair, or making that content more readily available by recruiting hesitant characters.
