Quote from XinhuanProbably neither. Since "DPS" is a fairly vague definition.
Is it "damage done / total time in combat"?
Is it "damage done / time in combat from first hit to last hit"?
Is it "damage done / time someone in your party entered combat to last person exiting combat"?
What about your pet that started attacking first, but you entered 10 seconds later, should your DPS time including that 10 seconds?
What if you died but your dots continue to tick for another 18 seconds, should that 18 seconds be included, but the moment you died, you already went out of combat? And should that damage even be included?
Different addons use a different variation for DPS calculation.
No idea lol.
