Gave Russia a go. Pogost, particularly its' upgrades, feel very underwhelming even when going wide (I mean well, Russia, 'course you're going wide, but anyway...). If possible, I would spread its' upgrades slightly wider tech-wise, and make them way heftier in terms of yields. Especially the third one is more faith in a part of game where you probably don't give much (if any) value for additional faith yields - if you have a religion, you're rather likely to already have spread it as much as you can, enhanced it and bought all the religious buildings by the time you hit Architecture (especially as going wide is already inherently better for raw faith gain anyway). I suppose it does enable Russia to get more leverage out of certain heavy faith-spending beliefs... if you did nab a religion anyway, as Russia has no helps for actually getting one - other than being encouraged to grab as much land as possible. Contrast the 'completed' Pogost to any other unique renaissance+ unique building and it feels rather weak. At least to me. Licorne is hard to comment as in combination with Enlightment Era you get it an era-and-half too early due to tech placements - obviously it's powerful when you get it way too early. Will have to play another game without EE.
