That seems to be a major complaint on most of these reviews that were recently released.
But IMO, this game will need a re-review in about six months. After a couple of patches and a map/game mode pack is released. MAG was kinda a crappy game when first released, and now it's an amazing game. It just took some time to iron out all the kinks and release a couple map packs coupled with different game modes.
I have faith in Zipper. And we know they will not abandoned this game.
