Who cares though really? I mean, chief is the worst part of the Halo franchise. The world around him and the conflicting ideologies are so much more interesting then he is (Fascism, Genetic manipulation and extreme militarisation on the human side and Religious Zealotry for the Covenant).
Loved Reach and ODST (even Halo Wars for that matter) because they at least tried to look at new and different things rather then just 'Lolz you are da Chief! Shoot those guys!'.
