SMn have ilvl 92

ACC: 487
crit 486
Det: 290
SS: 383

The start rotation I use is : SC -> SF -> RS -> B2MB -> fester-> ruin I -> Contagion -> Rouse-> ruin I (1 or 2)-> fester-> Spur -> ruin I -> Enkindle.

and refresh the dots at around 9 sec (individual, mean I no longer use B2MB but use w/e skill need to refresh) and put in ruin I and II in between.

according to other ppl, my dps in t6 is not over 200 dps (something like 192+ 70 or + 80)
and t7 at 50% is below 150

what I did wrong for having to low DPS ?
