Title.
I do not want to be forced to play human, I do not want to be forced to play Alliance for that matter. But if you want to compete at a decent level, it is almost a MUST. You shouldn't have to play a certain race because of its racial.
If you look at the 3s leaderboard you get a good idea of how broken and dominant racials are. The top 500 contains only 7 horde, and a gazillion of humans.
