I think the math is actually much more complicated than that... since NIN is an IFs-ridden job :/
Duality could actually give AE an insane priority... damage wise...
Lets say we have Duality at hand, but our current situation requests us to go DE » SF > MU » AC » AE.
AE is quite far there... as far as it could be actually (and happens quite often too). Lets say that DE will fall in exactly 7 seconds, this means that it will definitely not make it even to the SE of SF.
Now lets say for the sake of Duality we swap DE and AE position so it looks like: AE » SF > MU » AC » DE.
Duality would have an oGCD value of 352 (because it manages to catch DE), but what do we lose from not having DE for the next 9 actions?
SF -> 35
MU -> 6
AC -> 63
DE -> 61
for a total of 165 potency... against 352? 187
Now lets say we are a bit stupid and do Jugulate, Mug, Dream, Shuriken and TA in that very same 9 actions window??
Jug -> 8
Mug -> 14
Shu -> 24
Dre -> 30
TA -> 40
for a total of 116... against 187? 71 ...
Duality AE still beats the loss of DE... in a solo scenario...
If you have 2 other people benefiting from the slashing debuff every 2~2.5 seconds, don't even think about it :|
