While I agree that I haven't seen anyone _say_ Arco is overpowered, I believe it is generally considered one of the best nations.

Now, as to why it is overpowered...

The Witch Doctor is, what, only 80 gold now? He's still a pretty good researcher. He also can forge Fever Fetishes innately, and summon Mound Kings to carry them. He's not sacred like the Priestess, but he can pay for his own upkeep with the Fever Fetish. It's kind of a wash. In fact, I think these reasons are the ones they'd cite for reducing his research in the first place.
