I have decided on a final build for my level 70 dagger rogue.
41/20 Assassination/Combat

I tried full combat, and backstab basically sucks ass. The damage, the point generation, the energy cost, it's all weak. I feel slow, heavy and gasping for energy all the time. I even tried with a fast off hand to get Combat Potency going, but it was still only good when using Adrenalin Rush.
Assassination and Mutilate serves the dagger justice like Combat and Backstab did it before the 2.0 patch.
The guild will start raiding Karazhan at the end of the month, and I really fear my little rogue will put a strain on the healers. I have been doing a lot of Tempest Keep lately, and the mobs and bosses all have some sort of aoe effect that hurts like hell, but surely only affects players in melee range. I find it stressing to dps properly at times with all these ground and aoe spells. Thank good for Quick Recovery ("All healing effects on you are increased by 20%").
The hunter class is really blowing me away, the dps is in the same ballpark as all the other dps classes, but the usefulness of pets and spells is amazing. My friend has gotten tons of upgrades on his hunter, recently epic helm and bow from Thrallmar, and I can't keep up with him on the charts.
It annoys me a little that the rogue does not excel a bit more at doing the only thing the class was designed for. I bring very little to the table except doing damage, but I'm almost evenly matched (and sometimes surpassed) by other much more useful classes. I have low hp, low armor, restrained to close range, have sucky debuffs, no group buffs, can't do aoe. However stunlocking and interrupting a single target is manageable.
I guess Ced's Carver isn't showing the real potential, a proper pair of daggers will tell a different story.
