Edit: Ups, I was sure someone else would have posted something in the time it took me to write this.
Sorry for the double post.
I don't quite agree with that statement.
It's absolutely true that getting a 2, 2, 2 rep is huge. Specially as it gives as a firm grip in the entire center-south region of the Emerald Seas. Even if the boost went to the South River Jing we would still get a 2, 1, 2 rep and get rid of a negative region in the south. Neutrality is the best we can aspire to with the Peak aligned for now.
But a +3 reputation means that they won't just approve of our project, but will actually start to actively support it, however shyly at first. That's a huge difference.
Specially so since we have to continue with that Road Renovation Quest we picked up at Hanyi's concert.
Not only that, but (if I remember correctly) the Western Ferns are still at -1 rep with us. With the Meng being out primary ally in this cultural venture, that is concerning.
Even if it isn't said explicitly, the immediate bonus is for Fundations, I'm convinded that the Hanyi bonus in Meng projects will translate in an improved rep there.
I find that more valuable that the random chance of the other choice.
