Heh, Enweil. Iato just grew to a decent size. 2 months ago all regions were aligned to Fengen.
Observation bias perhaps, but I wasn't only thinking of Enweil. Maybe things changed recently, I don't know, but my experience has shown me that regions favour the capital over other duchies unless there are solid reasons not to.
D'Hara obviously doesn't count.
Well, many realms have a single duchy, so you need to exclude them from your calculations.
