Yes, the opening will probably be PS - IT - BS - BS - SS - DC - HoW - DC. Then, next refresh, PS - IT - SS - SS - DC - DC, and the following rotation you can start just pesting and such. You should have most of your procs and such up when you do that second PS - IT, but if you ever get more, simply refresh as appropriate. Simple enough.
Unlike Blood, it's not really worth us going through a set of runes diseaseless to get procs. We simply lose too much and gain too little.
Yes, agility to cloak will become superior.
In the latest version of the PTR, not only does the shadow portion of SS appear to be getting the additional crit from Subversion and Vicious Strikes, as expected. What more though is that the shadow portion appears to be getting the
crit modifier from Vicious Strikes. Yet another buff. Math to come once I can absolutely confirm.
Edit: Yeah, it's definitely getting the 30% from Vicious Strikes.
Which, combined with the higher crit change, makes things something like this:
| Physical / Shadow | Total Damage based on Physical | Total Damage | Chance of Happening |
| Hit / Hit | X + 1.11X | 2400 + 1.11 (2400) = 5064 | (1 - .5)(1 - .5) = 0.25 |
| Hit / Crit | X + 2.369(1.11X) | 2400 + 2.369 (1.11 x 2400) = 8711 | (1 - .5)(.5) = 0.25 |
| Crit / Crit | 2.369X + 2.369(1.11(2.369X)) | (2.369 x 2400) + 2.369(1.11(2.369 x 2400)) = 20636 | (.5)(.5) = 0.25 |
| Crit / Hit | 2.369X + 1.11(2.369X) | (2.369 x 2400) + 1.11(2.369 x 2400) = 11997 | (.5)(1-.5) = 0.25 |
(The 1.11 coefficient is including Ferocious Inspiration which I forgot previously since it obviously isn't present solo, and the 2.369 crit modifier is including the meta which I had simply forgotten previously, not that either terribly shift things. The main thing is the higher crit chance and crit modifier on the shadow portion)
So, yeah, that's an approximate 5064/4 + 8711/4 + 20636/4 + 11997/4 = 11602 average SS. About a 10% improvement over the previous PTR build, and something like a 55-60% improvement relative to the current SS. Quite delicious.
