oh joy, another lord of the rings rip off.
I'm sorry but thats how the early warcraft story felt, it was just good humans vs bad orcs, and for me, the story didn't get compelling until wc3 where the writers did something different.
Frankly, this is disappointing. I thought the lore around WC3 far more interesting, because it was varied and different. In that you have examples of good and bad humans and good and bad orcs, and it made for better characters then the black and white good vs evil crap.
