What if the Incas' team bonus was "Markets work X% faster" instead of their farm build speed?

Incas might be a powerhouse in 1v1's, but their team bonus is quite weak. 50% faster farm construction is pretty underwhelming, and doesn't actually fit them entirely.

Instead, a bonus like "Markets work X% faster" would be more useful and would fit the Incas' history better. Being able to build Trade Carts and research Coinage/Banking faster would be deceptively useful. That and being able to research Cartography in ~0.75 seconds instead of 1 second; that's really important.
