Making a Ping face the facing angle of a unit

Blizzard's ping-facing system is currently broken. In order to get a Ping attached to a unit and refreshed every 0 seconds to point to the facing angle of the unit it is attached to, you must use this formula:

Variable - Set Ping Angle = (((Facing of Unit_The_Ping_Is_Attached_To) * (2.0 / 90.0)) + 2.0)
