Civ discussion: Slavs

Hey again! A week ago, I posted a discussion about the Incas. I wanted to do another, so I chose Slavs since they seem great on paper but I dont really see them much.

Some points for discussion

• Boyars (UU). Are they good or basically a worse version of the Catapracht? Are they a bad unique unit for a civ that is supposed to be an infantry/siege civilization? Do they have hidden bonuses?

• Druzhina (UT). It makes infantry deal damage to adjancent units (a bit like catas). How good is it?

• Orthodoxy (UT). It gives your monks +3/+3. Are monks must to go for Slavs?

• Economy. How good is the farming bonus?

• Strategies. What is the best playstyle for Slavs?

• Overall rating. How good the civ is in general, and why is it good or bad. Also is their playstyle tag (Infantry/siege) correct?

Feel free to ask more questions if you have any, or tell your experiences of the civilization.
