These are still way over powered. Many USA players like to build ONLY gatling guns. I have a game recorded today that I played as Inca. I had only fully upgraded Chimu runners and would lose/break even to only gatling guns. USA just sat in his base with gatling guns most of the game and there wasn’t a thing I could do about it.
Here is the recording.

A trade monopoly won’t do any good if I cannot counter his gatling guns. At the end I even did the Tupac Revolution and gatling guns defeated my entire population which included many light cannons and all the settlers were muskets. No match for his gatling guns.
