H2 priests: Why, when, how?

[Sombre]

So which nations with h2 priests do you recruit them for?

At the moment it seems people are talking theory and citing niche examples where having +2 morale makes a difference. I think it's much more common that it makes no difference and the national H2 is a waste. And it's silly to compare it with just a support mage slot - it should be compared with a researching, site searching, ritual spamming mage slot. The general run of the mill mage you make almost every turn wherever you can. While the H2 is a near complete waste if he doesn't toddle off and support an army, that isn't true of the mage, so don't restrict the comparison as if it is.
