I was looking over the skill list for this class and I came up with an idea that you may or may not want to integrate.

It seems that the archetypes are such a key part of character creation (i.e. you choose Archetypes which best reflect your character's initial ability / starting party role) and I wondered if maybe there was a way to integrate that into your class skills.

I mean if you pick the archetype The Voice shouldn't you getting Bluff, Diplomacy, Sense Motive all as class skills? I know as a minor aspect you get an insight bonus to those skills so that stacked with getting it as a class skill may be powerful - but if you think about it if you're attempting to be the voice of a party before being 10th level you're at a severe disadvantage compared to another class like a bard.

The only thing about that is that this class is fairly powerful, I don't know if that would disrupt the balance of this class.
