Starcraft 2 Anti-Gravity Changes
Karune informed the anti-gravity ability has been changed from its original concept, thus some of the Q&A batches are outdated. In the current alpha build, anti-gravity cannot lift buildings, and cannot lift big units such as the Colossus and the Thor. The ability doesn’t cause any effect on air units either.
The anti-gravity ability is meant for harassment and strategic disabling of key units early and mid game.
