since the important part is the race I don't know why you want proof of class... but it's weird.Please show your proof that it didn't just get past 3 people, which things often do in writing. And show your proof that he was the assassin class and not just a rogue that was assassinating people.
as for why getting past 3+ people matters is these are supposed to be 3 at least have a passing understanding of the setting, and this mistake (and I am fine that we call it one) changed so little that it didn't make any of them see it as wrong.
so again, it doesn't make any difference.
