It's not something specific; I can usually understand where his quest is going ("kill them all and have done with it"), so I didn't pay him extra attention.
Then yesterday a friend commented that "you whayfaced cur" is not a phrase most people would use to insult their enemies...
So we dug up some of his dialogues, we were not native speakers, but at least I'm sure not all half-orcs talk that way.
I just couldn't pin this down, but it feels like something is very... strange... here. I know that I'm not good at English but I *constantly* need to google certain words he used, and the way he phrase most sentences... have you seen the way Gromnir talks?? You guys are both half-orcs and from the same tribe too, so I take this has nothing to do with childhood education??
I just can't describe the way he speak, WHY is he talking like THAT???
edit: Another friend told me he sounds like Rexxar. Oh.
