Query: Extremely limited perspective

An absolute waste of money! As it turns out, I've been diving recently at many of the locations listed plus quite a few others. Given the title, I thought the list would be quite comprehensive. I expect there will always be differences of Opinion on subjects like this, but I can't figure out the logic of the locations chosen. The authors maintain that ease of travel is important to them, then list Heron Island Australia, but leave out locations like Bali. My biggest criticism, however is the long list of East Coast USA choices.
