Out of curiosity, how useful are the grenade launchers? I'm a newbie and have never used them (or had them used against me), but it doesn't seem like they would be very useful. By the time you arm and fire your "shotgun blast", you could have just as easily fired a few dozen BBs in a nicely aimed burst, couldn't you? I admit they look cool (which is good), I'm just wondering how useful they are.
