So here is what I have found: duty finder group matters. Time of day matters. Which dungeon matters. I found out that during NA prime time, avoid duty finder like the plague. But that only seems to be true in certains groups. So I have characters in 4 of the different DF groups because I am so spread out. So in other words: some of the people complaining truly only ever see the problems, because when, and where (and what) they run they have a statistically higher chance of seeing it. Like all the problem players are running at the same time, in the same groups/worlds.

Does that make sense? I have had more good experiences than bad, but when I have had bad, they always seem to be in the same places and at the same times of day.
