Godamn Poland is good, an entire free policy tree? Why thank you, ducal stables are also great, especially if you get a good amount of cattle, +15% production on top of half the Huns UA and no maintainance? Hell yeah.
Winged Hussars are a bit meh, bad upgrade path, but show me a civ that doesn't have a single lackluster feature, and I'd rather have it be the UU then the UA, UI or UB.
Spain going down, interesting but ultimately kind of pointless UU's, with a UA that is a complete waste most of the time, especially if you play certain maps, on the earth map for instance the only wonder you'll ever find is Fuji, yeah, that's really gonna help.
Like Japan but without the damage bonus.
