Diplomat class idea and questions

[hurderion]

Hello! I have been thinking on how to create a new class called Diplomat.
Its main mechanism is to convince others to join his cause and fight for him or by neutralizing the threat by, well, making it neutral instead of hostile.

Can have permanent party members.
Can have initial, upon zone enter and just once per zone, allies based on which zone it is, like bodyguards provided by the "host nation".
Can turn enemy into friendly, without direct control, just an ally into the player's faction.
Can turn enemy into party member.
Can change enemy's personal reaction to neutral regarding the player.
Can set one or more enemies against another, by changing to a third faction that is hostile to its original faction or changing its personal reaction.
And more, but variations of these.

Of course there are no addons similar to this, so I could not see how to implement such skills.
Is there a way to get enemy's faction and/or personal reaction and change it?
And change it to the player's party?

The Yeek racial talent Dominant Will might help for changing a target actor's faction. As for having permanent party members, that sounds kind of similar to what the Adventuring Party addon does; I haven't used it, so I can't say if it's what you need, but that's the first place I'd look.
