Spec question/dmg outputFollow

I'll leave some hemo people to comment on that one, but will try to comment on other items...

Looking at your spec I'd take 3 points away from MoD and put 1 into relentless strikes and 2 into weapons expertise. That should immediately improve your dps.

I wasnt quite sure why you were spec'd for both swords AND maces, but am assuming that you are using the build to pvp and pve and are switching weapons. If not, stick with swords and move the points into Vitality and Murder. That should be even more dps.

Your ap and crit are good so gear is not an issue. Hit rating isnt too bad either given progression.

1s&d,5s&d,5rup would probably be right, I don't think your technique is too wrong. I am assuming you are mh deadly and oh instant.

Being low on curator is an extremely unfair comment. It is the one fight where it is harder to be top on dps (especially given locks and their 10k+ curse of doom hits on evocation). Also curator is poison immune so you loose roughly 10% of your damage right there. Rogues need to build combo points and stay on targets to get their optimal dps, so you will generally only get one or two (maybe three at best) points on a flare before it will die. If you are staying on Curator the whole fight then that is another story and yes I would expect higher dps then.

You should ask him where you sit for nightbane and prince. Those are boss fights where you should be 10% above everyone else.

5/5 Mace Specialization while using two swords?

My experience so far is that we either move the Prince away from the infernal, or we wipe - and then it "does not count", heh.
Anyhow, I mentioned it here as with good use of CoS and lucky infernal drops I was able to reach pretty high DPS. So it can be used for measuring.

I left out Illhoof on purpose. First you have the chains that mess up the cycles. Then you can use flurry to doble the damage, and there are the times with increased Illhoof vulnerability. I think the end result is somewhat unpredictable.

Outside of Karazhan I like Nalorakk best to measure DPS, as he barely moves and there are no target changes.
I have very little idea about 25man bosses.

Re-spec to something like this and you should do better.

You're gonna lag behind a little on the Curator fight because you probably spend most of your time chasing flares.

I agree with Theo that Nightbane is a good fight to measure your DPS on since the most moving you will have to do during phases is if you get charred earth under you.

Illhoof works as well, but if the imps are close enough a BF/AR combo will skyrocket your DPS.

Thanks to everyone who replied. My dmg output for the fight was down bout 100dps so around 600. he said his prob was that he put out more dps than me on his shaman in blues. don't think he understood i couldn't build combo points or what not on mobs that die so fast. to answer the question about the 5pt maces i was tring out a hybrid build to be able to pvp and raid with. i've got fools bane and another mace in my bag, however after looking it over i noticed that the 5pts in MoD and maces could be put to better use to up my dps. lol just gonna have to respec if i wanna pvp(shudders at respec bill) lol. gonna test out tonight on shade and such when we clear. Thanks for all the imput everyone.
