VRS certainly isn't a myth.
It does of course exist, just the probability of you running into it or have an accident as a result is slim to naught.
Like LTE, the common DNA is a sudden and unexpected loss of talent, usually demanding too much power, too quickly from the aircraft.
While VRS in it's early stages may increase power demands, a properly flown approach, within the capabilities of the aircraft (or pilot) should leave sufficient power to cope.
When you tend to see these accidents that get blamed on VRS, it always is a case of power required > power available.
In the more third-world nations there seems to be a desire to fully demonstrate the bounds of ones abilities, this usually ends with the local Agusta, Bell or Sikorsky rep buying a new sportscar.
