I've noticed among the couple people beating me in rankings, I can find no difference in the rotation, then I armory them and see that they have foregone the 2600 haste while still running insanity, and are using full mastery with it instead. Did I miss something?
Do we know at what point that becomes the better DPS? All of them have a LOT of sockets on their gear, which I figured might have to do with it. Does it depend on how much mastery (i.e. how many sockets) you can achieve after dropping the haste? Is it just based on the kill times (i.e. having heroism to push you to the threshold instead of static haste) and does it end up changing the rotation? Sorry if I missed this, but I've been having other shadow priests ask me about it and I must admit I'm in the dark at this point and not seeing any other threads about it :P
