Obviously trolls or fanboy of another MMO.
Their comments show their complete ignorance of the game.
I have quite some gripes with SWTOR that I hope BW will fix soon.
I have seen other problems mentioned by other players too.
And the comments on metacritic show none of the above.
So yes pure trolls.
Get used to it because this game is gonna be popular, so it'll attract a lot of hate for sure.
