That's not just because i want. In the first place, they found a new world and they did it, because they have crossed the ocean. No matter if i play them myself or AI instead, they found anything reasonable. I don't say they are weak unit for combat, but their UA is wasted most of my games. AI too much willingly settle their continent. Don't you think it would bring much more fun into them and into spain overall? it does not sounds to me broken, but funny hell and finally the reason play them. they are boring.
Edit: Another question. When market-like buildings got buffed(bank providing huge gold to caravansaries/ch), would not be possible buff somehow satraps court for persia? i think +1gap and gold for every 5 people is anything shiny, merchant slot is fine, but in the matter of obtaining aditional GAP for Persia, those 3 above mentioned buildings are much more important than their own UB. Maybe add satrapps court into Bank buffing list, or increase military cap by 5-10% from that building woul not be bad also.
