Bullshit mechanic that prevents the game from being competitive.
It basically boosts the other players team in every way to make games more "interesting".
Some of the signs are:
- Opposing team AI players being on super star difficulty while yours are amateur level slalom sticks
- Checks from behind normally don't do anything but suddenly a check from behind sends players flying
- Not being able to pick up pucks, simple passes won't connect
- Goalie falling on his ass all the time after a save and giving juicy rebounds
- Your players not being able to hit the net no matter how good the stats are on your players
- If you manage to get a shot on goal there's still a spider goalie standing on his head to beat
- Your goalie letting in backhand shots from blue line
- You get the puck in your own zone, no one breaks out to neutral zone no matter how long you look for an opening pass
etc. etc.
It doesn't happen all the time but when it really kicks in it sucks all the fun out of the game and you just want to snap the disc in half.
