H2 priests: Why, when, how?

[Jarkko]

I have never quite figured out how to use H2 priests properly. Ok, so they can cast Sermon of Courage, they can preach a province to three candles and they can site search for H2 sites. However, this comes with a price, a price which I think is pretty steep, so there must be something I am missing.

I've tried to look at the H2 sites. Not something to call home about, is it?

Two or three candles, does it make a difference? Usually you can buy at least two H1 priests at the price of one H2 priest, so if you are preaching to defend your dominion, isn't two H1 priests *always* better than one H2 priest? If trying to reduce a hostile dominion then a H2 priest would be *almost* on par with two H1, unless the priests are inquisitors, right?

It would be purely lunacy to make a H2 priest to prophet, wouldn't it?

Sermon of Courage. Ok, I have to admit it, it is good. But is SoC the only real reason to go for a H2 priest instead of a H1 or H3 (altough H3 priests are in some cases capital only, and they might be old too)?
