As Terran facing a Protoss. The Protoss goes for a standard army, Gateway units with Templars and Colossi.
The Terran has a standard bio ball with a few Ghosts and some Thors.
Does the Thor High Impact Payload work against Colossi?
IF YES: Is the Thors High Impact Payload worth using versus the Colossi or is it better to have the Thor focus the Gateway units?
