Simple edit: as far as I know only thing they changed was that they moved the nat minerals away from the cliff and into the nat more. This means terran can't tank protoss' minerals, and FEing is a little easier pvz.

Trooper is back from like a month away, actualy the main reason it was moved back because in pvz muta harrass was so effective on the nat cause toss couldent build cannons behind min line and same with turrents for terran
