LOL. Stop overrating MAG's teamwork aspect. Being a MAG player isn't going to make you better at this game than someone else.
Here's some footage of ME playing MAG, for anyone who's wondering just what the heck the OP is rambling on about..........

Wow, because I did mention 'teamwork' as one of the similarities in MAG. It seems like you just used this post to show off and boost your ego. Now, where this game draws parallels with Brink is that it has a series of objectives, where some of them are of higher priorities, and it also forces you to manage more things rather than just running around for kill. However, since you seem like the type of person who reads what he wants to read, I'll give it to you in a simple question.
Do you think that if you had played BF2BC, COD, Halo rather than MAG, do you think you would be equally, or better equipped for the added complexity Brink has?
