I enjoyed Face Off. It was something different to do and the smaller maps kept it interesting. I don't know if I would trade regular sized maps for it though. I played a lot more of the normal 6v6 than I did the 3v3's.
I miss having 2v2s. That was my favorite feature in MW2. Me and my friends played it all the time. I definitely think that they should bring back 2v2s and 3v3s!
No. Face of did not work as anticipated, good idea the community simply is not ready for it. The amount of boosting, idiotic playing was too much.
MW2 did not have 2v2 or 3v3 that was MW3 with the face off lists. And it was a complete joke because of the maps made for it and how small they were to force quicker action. Plus the spawns in those maps were way to predictable and easy to camp.
Plus it cannot be be brought back to this game for it was never in THIS game. Added, maybe, but not brought back. And as toward adding.. Nope, not needed when there is League champions which is a 4v4 and that is as small is as needed. Want smaller, go play custom games.
