Massive changes to Mapuche, Canada and, especially, Khmer, who will now be an absolute faith juggernaut. The ‘major adjacency to holy sites from rivers’ bonus alone has the potential to be amazing, let alone the other buffs alongside it.
More dubious about Spain: they’re still very dependent on settling on foreign continents, which is sometimes entirely out of the player’s hand. Then again, Victoria makes it work, so perhaps Spain will finally glue together.
I also noticed that Georgia’s Khevsur now replaces the new Man at Arms unit – i.e. you can prebuilt Swordsmen and upgrade into it (at Military Tactics, presumably). That’s a huge buff; and I assume the same will apply to Japan’s Samurai, Norway’s Bezerker, and then a few others for the ‘Line Infantry’ unit as well (eg. Redcoats or Garde Imperiale).
