The no1 priority for Blizz should have been to differentiate from the Kung Fu Panda theme as much as possible ... The theme is great, but childish. No chubby pandarens. That was a mistake. No2 priority was to give players a good villian ... Garrosh is a retard, pig, retard, just no. Tentacle monsters are not a good villian either.
tl;dr If pandarens were savages and there was a proper villian, I wouldn't hate them.
