why the hell can't you use the booster sliders in franchise, playoff or any other mode besides exhibition-game??
when I play an exhibiton-game and turn the booster up for goalies I seem to get the perfect edge I need to have the perfect realism...but in any other mode u can't use that so I get killed in just about every game, since they seem to be scoring whenever they feel like it...and I can't turn the shot accuracy down either cause my scoring is still on the same level...Is anyone else experiencing the same problem, or atleast have an idea what I should do it would be cool to hear that...
