Affliction has a lot of downtime doin nothing, happens when everything is dotted and it is time to MG the target.
It stands there and does nothing, waiting for something!
u can see this in my log at timestamp 18:37:03.277, seems to be an issue with the potion usage (not completely sure, i understand basic rotation of affliction, but some stuff is a bit weird for me, but it looks like it is an issue with potion usage and not rotation itself)
Lil description of the whole situation/fight:
Basicly this is a 3 Target fight (Protectors in SoO, 3 boss encounters), with sometimes a lil bit more enemies (we didn't reached that phase, so 3 target fight)
the High AOE-Count was set to 4, so "all" the routine had to do was ... multidotting and MG
Because of the amount of mobs, there should be enough time to multidot everything and cast 2-3 MGs in a row before redotting is needed.
Remembering the Procs for stat increases, we reach a total amount of 1-2 MGs before refreshing the dots.
But in this fight i had a pause situation of 10 seconds or more (from log i would say it is the potion, but haven't had time to inspect this ... we needed to progress a bit this day

so i switched back to destruction)
