I had some issues keeping hate from the Monk and BLM that I rank through SV HM with the other day, but I'm sitting at around 85 ilvl, and they were both all ilvl 100 gear, so it's rather understandable.

Not sure if there's any truth to this issue overall, or if it's just that dps are 'way' overgeared for these ilvl 70 req dungeons.
