In Heart of the Swarm, the Thor's Strike Cannon were removed, replaced by an ability called High-Impact Payload, which is supposed to be good against air units. But what are the details; I cannot find the numbers or good discussion of tactical advice for it.
- Is High-Impact Payload better against all air units?
- Can a Thor still attack ground units in this mode?
- If you are under air attack, is it worth it to shift modes, or will the conversion time reduce any benefit of the High-Impact Payload? (Like Siege Tanks caught unsieged)
