LOL jao, actually unless youre playing the usa squads against themselves, they are useless... they are no match for any team in the game, everybody knows that... it was fun one time or two , and that's it.. it's over. lets return to mycareer or something.
That said, it's still kinda cool to have them in the game and once we get all the tools we need to start producing detailed roster updates, those assets will be handy in creating historical teams.
It was something different to play with out of the box and as I said, the assets they provide will be handy once we have the REDitor and the ability to make more detailed historical mods. It was worth putting in and worth hyping, though the replay value is certainly limited.
