While I appreciate the desire to get some opinions on a variant that you've found success with, you haven't really given us enough information to comment intelligently. Your suggestions are clearly inferior based on the established theorycraft, and while I'm totally willing to believe we may have made a mistake, "I tried this and it was totally awesome" isn't really enough to make it worthy of additional thought.
Basically: if you've done significant and systematic testing, by all means explain the nature of it and we can examine it in that light. But if you just ran two weeks of raids as each and maybe did a bit of dummy testing... you got lucky. There's nothing else to say, and we don't need to hear about it further.
I've been running a slightly tweaked spec and have seen a major boost is dps. Basica;;y 1 point relentlessness and maxed out Coup de Grace.
Talents & Glyphs - Game - World of Warcraft
For those wanting to see my set up. Doing this caused a major dps jump +1k ish. I've ran with it for awhile now and seen it wasn't a fluke. Anyone out there able to better explain?
My current thoughts on this being I generate combo points fast enough already that I don't normally have to worry too much about relentlessness procs. And the increased damage from evis makes the dps talent worth taking(Doubling it's affectiveness when I have to Blade Flurry as well).
Other issue I have found (please correct me if I am wrong) Is the rupture only being a 1% dps loss. I've found a dramatic drop in dps not applying it than I do with it. Does shadowcraft or rawr effectively model BG into their numbers?
Last thing I was interested in other rogue opening dps rotation. On fights I don't have to be in a specific place (thank you domo). My opening rotation is SnD 3-4 CP burn AR get rupture up and then go to evis (4 CPs from SS and then RVS unless SS glyph procs the 5th) until AR is down. At this point in time BG is at 30% I KS after I empty my energy bar and then keep SnD ruptre and evis able to.
Thanks for the imput I look forward to the responses.
