I'm looking for some tips to increase my ninja dps. I mained NIN when I started playing ARR, so I'm already familiar with the normal skill priorities (switched to AST for the static when 3.0 dropped and only just switched back to NIN 2 weeks ago). I'm specifically wondering about when to pop certain skills and cooldowns. Typically I reserve IR, BfB, DWnD, Duality (with AE) and Kassatsu for when Trick Attack is up. However, I've seen other players suggest always using Duality on CD, pairing it with AC instead of AE as necessary. Similarly, I've heard Kassatsu being used on CD as well.
Since I try to Trick Attack on CD as much as possible, it's obviously difficult to get the timing right all the time depending on the encounter (no rear access, boss is about to phase change, be invuln/out of range, etc). I fear that if I'm always popping things on CD and not saving them for when I get that TA timing right, the CDs won't be available for use when I do get the TA off.
