Pro-Gaming Life - "Mules, mules, and more mules! That’s how Terrans can afford 1-1-1s or any other “take the whole scv village to the battlefield” strategies out there. The coming patch hits them first by making them harvest THE SAME AMOUNT OF MINERALS in high yield (yellow) mineral fields. That’s right, Terrans can no longer mass mule and exponentially push a Terran’s advantage in high yield minerals. Of course, this is only considered a nerf on maps that have them attractive yellow mineral fields. So if you’re a pro-gamer participating in the Global Starcraft League (GSL), you can disregard this part."
