I was getting ganked about every three hours on average, and that was while multiboxing a 3 or 4 man group. So yea it was the worst. But on the lighter side, once you're out of there, I was never ganked in Blade's Edge or Netherstorm - presumably because 70s steer clear of those zones as the players are higher level and ganking becomes more difficult, but also because the zones are more sparse and there's less for 70s to do there.
