This is the issue i have with this. Obviously, Garrosh is deranged, a tyranical dictator, who just like the evil warchiefs of the past, says that the 'true horde' is the one he leads, right down the shitter. You would think then there would be more standing on what the true horde is (the other races and some of the rebel orcs), and that of the corrupt leader (Garrosh's horde), and you'd think Nazgrim would pick up on this, as in what the horde is meant to be, not what Garrosh makes it out to be.
this current story should go more into depth on the meaning of the horde, having characters actually realizing what the horde is, what it means to stand up for something you know to be right, instead of falling into a clique of 'honor and duty' above common sense.
