-Tempest deal +14 massive damage to air.
We felt that by removing damage to massive, Tempests simply became too weak versus Colossi. We wanted to make a damage change to Tempests that would severely change how they interact versus Brood Lords, while less-severely affecting their relationship against Colossi. Changing their massive bonus to +14 felt like a good number because it doubles the number of shots Tempests take to kill Brood Lords, while changing the relationship vs. Colossi by about 67%.
