While I agree any spec would see a loss of DPS with certain raid members dying, HaT gets hit harder by a party member death because you'd lose a source of combo points along with the raid buff they were providing. I can see the progression spec argument going both ways. In certain scenarios like you being one of the last alive, your DPS would be gimped compared to a typically specced rogue. On the other hand, your defensive CDs may allow you to live longer to finish the boss off. In any case, I think most rogues would agree it's a pleasant surprise that there might be a 3rd option later in raiding.

I've only really seen one mention of Shadow Dance along with HaT and have yet to see anyone specced for it as well. I've only mentioned it in terms of playstyle comparison not actually stating it's a viable use of points. I don't really know what you mean by others.

Hope everyone has fun sleeping 4 hours a day on their way to 80 =P

I don't know where else to ask for this information so I'll start here.

Has anyone ran numbers or done anything theorycrafting for a Mace Combat build and how much dps is generated over or under a Sword Combat build?

I'm pretty sure spreadsheets handle that. For the most part I believe with equal quality weapons, mace spec still loses.

I am quite interested in the hat builds because of the opportunities it opens for us. One example is that we will be able to spam deadly throw in no-melee fights if we group with hunters. Can you post a WWS report of your fights? That way we can analyse the fights ourselves.

Deadly Throw spam would be good on fights like the high king during whirl, gargoyles that are not quite low enough in hyjal, striders on vashj while waiting on naga spawns, supremus chase phase, or other similar fights where you cant stay in 100%. Atleast, it would beat doing absolutely nothing waiting to get back on target.

Two questions, with a HaT spec would you want to get daggers for CQC or would swords do more dps?
And some post say that in 25 mans the rogue never has a down time on CP, but HaT works only in group wide, so do the extra CP come from gear or are they getting more CP form critting raid members?

1) To get the most out of your poisonprocs, you'd want very fast daggers. To get most out of the occasional hemo you'll be throwing if your group isn't optimal, you'll want another weapon. Preferrably fist weapons, so CQC would still apply. Swords would be behind these two options.
2) The extra CP come from the crits within your 5-men group within the raid, which depends on both the gear they (including you) wear and the buffs they have. Obviously, in a 25-men raid there's a bigger chance to get all the good stuff in buffs than there is in a 10-men raid or a 5-men party.

You would still be using wound poison and deadly poison on your weapons.
