Why in the world would they want to unbalance the game? Why would logically thinking developers waste their time desiging a game that is unbalanced. How could they have the ability to create a product with such potentional and then 'piss' it away with a lack of game mechanics design... simple, fact... they wouldn't.
Quite honestly, you seem rather naive. Having worked in the video game industry, let me tell you that developers are human, like anyone else, and if they enjoy the game they're making (and they should) they will have preferences and bias over one race, class, or whatever over another. Where I worked, almost every time there were arguments whenever a class or mechanism was going to be changed because one or more of the developers loved that particular class or race or whatever and didn't want it nerfed. Another thing is that usually whatever the most powerful guy in the office plays is whatever's going to be the strongest. Usually.
I am not saying that Brad wasn't joking but don't assume that developers are unbiased or impartial when it comes to game balacing. Having said that, just remember that sarcasm never works online.
