Marignon CotS - What's the hook?

[jaif]

I'm missing something. I started a game w/the CotS theme, and while I like it I'm missing how it's any better than the base theme, other than trading sailing ability for superior mage-priests.

What's special about CotS? Do they get a better spell later on like Tien Chi?

Btw, if I could petition for something in the next patch, as a newbie it would be putting these tidbits in the nation selection screen. So when (for example) I click on ulm, see a special theme called 'Black Forest', I can click on that and see that they can summon vampires and then be able to see the actual spell so I can plan my pretender accordingly.
