Tbf, you´re not entirely wrong since Oda usually likes settling things in 1v1s and the armies of fodders can technically be COC victims, but Oda can sometimes be schizo and have characters act like the Yonko having thousands of fodder is super important. At the very least though, I don´t think Loki would have a higher bounty than Big Mom and Kaido. They have decades under their belt, RP´s, and they have some sort of connection to the ancient weapons, accident or not. Loki not having proper backup is probably how he did end up getting captured, though I think that´s going to be situational and not a proper 1v1 loss.
