Anyone else feel the Inca are kind of underwhelming?

They seem to be really strong at defense but their units don't seem to do enough damage in general to be good. I think their early commerce age is super strong with the early TC and their free buildings... but closing out games later on has been difficult for me.

The jungle bowman in particular feels weak to me, which is disappointing because I was very excited about it. But the poison feels completely negligible, their damage is pretty low, and their range feels kind of lacking if they are supposed to be a defensive unit. And if they are supposed to be ambush units then their damage is WAY too low.
