after talking to the gm and his brother, for some time, he finally told me what his real Problem with me was.
He likes it, if all goes the way he did think it out, but i did always act in a way he did not think of, or in a more complicated way then he did expect. thats why he dont want to have me in his campain, because of my CN playstyle i did not fit in.
I'm pretty sure my english knowledge comes from Video Games, I did always join international Servers and guilds, it is much more fun if you have a Group of People from all around the world.
