When P makes mistakes, they tend to be more crippling. A single missed forcefield, or a poor engagement, or a misplaced cannon can instantly end the game for Protoss, and as a result Protoss players look far less consistent in the GSL.
This is true for every race in every matchup...
Honestly its not really worth worrying about, 100% every game you lose you could've won if you'd played better and there's no reason to blame anything on imbalance at this point.
