FFXI never had a dangerous world. You either learned quickly how the more dangerous mobs aggroed and just avoided them or you stocked up on Silent Oil and Invisible Dust, completely trivializing any threat besides the occasional True Sight creature. I didn't play EQ very much so I can't comment on that. This is also the kind of thing that starts out fun, but it quickly becomes a tedious chore if you have to pass through the "dangerous" areas a lot.
