Totally, but I don't know if it is the HFA or not. I have heard complaints about this even with it turned off. I haven't tried much myself, maybe tonight. I hate the way the atmosphere isn't the same without it tho, it's too bad the crowd doesn't get into it as much when it is off.
I wonder if that affects the impact players causing my rb to fumble 2-3 times a game as well (see my thread).
