Was testing out your sub version, was pulling 27k on a dummy (I have really good gear, 400+), you have implemented UI options of assassination and combat ... UI options NEED to be added for sub:
-Normal rotation (backstab as main ability)
-Hemo rotation for fights like ultrax
-Enable/Disable Shadow Dance again for fights ultrax (would be really pro if you could have a Shadow Dance option where Shadow Dance would be used on ultrax but only Premeditation is used to add combo points while still maintaining a hemo rotation)
-Enable/Disable Shadowstep
If you could implement that this CC would have no competition
