Average out Goths as a civ counter or get countered

Agreed. That’s why I think Mayans should get supplies. It’s still going to be rough but it would be an alternative option in post imp to selling resources and barely making any eagles:

The issue with going eagles is how much gold you’re spending and food for upgrades.
1000F 700G eagle line upgrade
750F 450G El dorado
and then you continue on spending huge amounts of gold on a unit itself - 20F 50G.
I don’t mention blacksmith upgrades case both players gonna get the same in this situation.
