Can't believe I had to make a seperate post to get people to pay attention to this list and use it as a reference point. Sorry if this comes across arrogant but I do not mean it as such, just as a way to get everyone on the same baseline I have figured out without being overlooked time and again.
I have simmed the weapons and such for single and multi and with gloves or shoulders offset and it seems the highest I can get with the latest simcraft is with the infernoflame staff and a tad more with the shoulders offset rather than the gloves. as far as the weapon I think it might be because there is more mastery on the infernoflame staff than the doomstaff and our dots still greatly benefit from haste so its more of a wash as a lot of our damage would still be coming from dots in a multitarget situation. Now for the multitarget situation I used BoP as for sustained multitarget where you always have 2 targets up it seems the way to go unless im mistaken.
As far as the trinkets go, I can see them competing with heroic trinkets but I am not so sure they can compete with the mythic ones. If someone would like to do the exhaustive trinket comparison be my guest, I have posted my findings for the BiS list.
here is the simc gear i came up with

One note, I did find that it seems that at around the value of haste this set has its scale starts to plummet, if i reduce the haste it goes up significantly. That is probably why the infernoflame is pulling out ahead is that without it the haste value is still high.
I will post the simc dps values I got from this list when i get home from work tonight but if anyone can come up with a list or changes that sim higher than this one in most cases (not interested in a list that sims higher in one case out of all of them as no one is going to gather a 2nd set of gear for one fight) I will update the list accordingly.
Until you come up with compelling evidence other than "but the theory says mastery is listed higher than haste" from a sim perspective, I will keep the list as is.
