Bored oft he typical world standards- the humans have overcome this habitual state and became much more powerful than other races. In true, they are maybe not so fire-resistant as the Dverger or Cait Sith but they have excellent survival skills and can handle with the most difficult oppressions. Furthermore the King Arthur is a human too. We can maintain that human in the world of Camelot are much stronger as we, but their advantage is that they are still human.
