Playing sub rogue in this season is annoying.
To be honest S1 was more fun due to Tierset removes annoying mechanic to play around Danse Macabre and other annoyances.
Rotation is more complex than it must to be.
You need use flaggelation before rupture and shadowdance, now you must use shadowdance with backstab and symbols then use shadow blades and just pull secret technique then you can get random proc for stored combopoints, then you just need line up within 2x2 SD,SD your second secret technique with cold blood because tier set bonus need time to ramp up. Also without cds you can use only 1-2 of your SD,SD cd meanwhile you need think about delay coupe de grace (20s- of main cds), you need to know when you just can pull of empty secret technique etc… a lot of things to track.
To be honest is fun, but in many situations it feels rly clunky to play. Meanwhile BM tier set just pumps xD our is kinda garbage.
I would like to see removal of danse macabre (we are not WW monks) and shadowcraft, terrible, nonintuitive.
Find weakness… just make backstab crit even in front. Its kinda annoying when you have cd downtime like 30s- and you just backstab,backstab, evis/rupture 
without find weakness.
Kinda still having fun with this spec but getting annoyed by super punishing mechanics One mess up makes your dps just non existent. Burst is kinda strong, but then you need play properly otherwise you never be seen in top 5 dps in meter.
