I know what he means. Once you create a character, you should only be able to play as the faction you chose (unless its story mode.) The story would continue to change based on which side is winning the most matches.) Inspiring new maps as well (?) When you play only as a certain faction, you may have more fun due to loyalty, a sense of belonging to the faction, and rivalry. With this, in-game guilds would have a purpose. Like for example, not only would guilds be fighting along side their faction, but they be fighting eachother over which is contributing to the faction the most. Lots of competition = a great game. I like the idea dude. 
Then again, I can see wolf’s side too. People are already complaining about not being able to change characters in between matches or something. Imagine how much they’d complain if you couldn’t change factions, ya know?
Sadly, you wouldnt find that in BRINK because if it were to be included in a DLC…ppl would complain. That would’ve had to be there in the first place. You know what I mean? People wouldnt willingly adept to a change like that. It MAY be good for a sequel (definitely for a new game) but not Brink.
