I'm a little confused as to why the Incite Rebellion talent for the Agitator keys off of Coercion. There's nothing in the skill to indicate that it's used to sway crowds, even when you're trying to make them fear something. It's an intimidation skill.
Leadership, on the other hand, specifically talks about this. In fact, the second bullet point says "[w]hen acting in a public venue, a character may use Leadership to sway a crowd to take action, most commonly of a political nature." That seems like exactly what Incite Rebellion is trying to do.
In fact, the description of Leadership seems to play very much into what an Agitator does. I'm confused as to why Agitators have Coercion as a specialization skill but not Leadership.
