Terran doesn't exists.
Good balance.
Revert mule changes and make protoss expand after cybernetics core how it used be, terran needs pay 150 for orbital in order to expand, so protoss now have natural sooner and that's where all the problem begins and rest is mules nerfed + protoss didn't start with 50 energy on nexus, lotv chronoboost is little weaker in terms of overall time. But it lasts longer, so lower multitasking is required and in hots where protoss had to chrono more freuquently he would forget during battles and human error, noone would chrono perfectly, this longer chrono is easier to exectute.
