This.THIS! This annoys me to no fucking end. It's like they already know they got it wrong but don't care to change it in fear that they'll look even worse. His name is not Hordy, Funimation. Please. And if I hear one more "King-sama" or "ANYTHING-sama/san/kun" I'm gonna flip.
I don't think there's anything wrong with using honorifics in subtitles after a person's name. That being said, however, I DO have an issue with them using King-sama. Using honorifics for a person's actual name is one thing, but my issue with the latter is that they are using honorifics after a person's translated title. What's the point? As others said, Your Majesty or Your Highness would work just fine. I just don't get it. The same applies to other varients in the FUNi subs such as Mother-sama, Father-sama, etc.
As far as the quirky One Piece character endings such as jamon in the most recent arc… well, that's up for debate, but it's a bit hard to deal with those types of things. Especially what's-his-face with the bogan stuff. But it's not impossible to translate them.
