800 dps isn't possible at all on PLD even with full slaying and sword oath. Best I can put out is about 500 dps in the case of a typical dungeon boss. That's average for the pld's around me as well. WAR can push out more. Seen them do about 800 if they care about their job, but that too is in full slaying while in dps stance.

Not sure how you guys are adding up your numbers, but I guess I don't know or everyone is trying to make themselves seem greater than they really are.
