Madrasah is such a terrible tech as it is right now. I’ve seen many discussion on this topic, but I think that saracens should not be a civ that should move towards monk usage at all. Instead, I would propose a another tech.
This would be “Grand Bazaar” (600 wood/400 food). This tech would upgrade Saracen Markets to “Trade Centers”, at first, trade centers would be Markets with double HP and some more armour. The Saracen Trade Center would increase saracen market bonus by 10% or 20%, also cheapen Trade Carts by 10%.
If you want to expand it even further, could give the Sarcens the ability to train allied unique units (mercenaries) in their castles, but at the cost of only gold (and at a greater cost, of course).
This would make Saracens a civ very reliant on market usage. What you guys think?
