I've heard it's ok, but it has some MAJOR flaws that seriously detract from the gameplay.
My friends said that you can snipe someone with a regular rifle from hundreds of yards away because the bullets don't stray like a normal.....weapon. They go in a straight line, so theoretically you could snipe someone from across the level if you could see them.
Also, the vehicles suck (apparently). I've heard a person with a rocket launcher can take them out easily instead of you having to go to work on them like in BF. That sucks! Vehicles should be nice and sturdy......not being blow up in two seconds.
I've heard to stick with BF:Vietnam also
