Kids these days . <| sep |> That ' s an interesting one . While you would never attribute a 10 % increase to NIN from the WAR ' s presence , since NIN putting up Dancing Edge is FAR from a 10 % DPS loss , you can most certainly attribute the AEs NIN gains to WAR ' s presence though you would only attribute the difference between DE and AE as the gain . Also sometimes there are fights where there are multiple tank targets , like A 1 S , A 12 S , and A 11 ' s EDD , in which case the Dancing Edge becomes legit again if paired with the nonWAR tank . That ' s when you ' d be putting NIN ' s presence as a 10 % gain for the nonWAR tank for the duration WAR and NIN are targeting separate things . That ' d be very fightbyfight and probably way too large a hassle to calculate in something like fflogs .
