Okay, i agree with you.
But here is the thing: The level of the group was below the carpet. We disliked it, so wanted a change. It would prevent people to get down to that level again, but also not to make it too serious to be more Role-ing and less Play-ing.
When Amar heard about Bern getting the "leading position" of this group, he was afraid of this exact thing. That the new world becomes more important than the players inside.
Now you might say, that you only want to have a proper roleplay, and Amar should really be able to adjust. Its easy, no doubt. But why?
Additionally, im sure that you would accept an Am'ar Graados with the same personality, same outfit, same jokes, but with a proper backstory. I find the argument about trashing the character because of it's backstory rather unpleasant
