Thought I'd post some questions/thoughts about some of the talents. If anyone knows answers please let me know.
Butchery: How will this work in regards to the 1 "runic power per 3 seconds". Does this mean you will lose runic power out of combat at 1 runic power less per 3 seconds and gain 1 runic power more per three seconds in combat? Or will you gain 1 runic power per three seconds out of combat also, effectively meaning you don't lose runic power out of combat?
Blood Rune Mastery: Does this apply to all hits, abilities only, or blood abilities only?
Are Blood Gorged and Bloody Vengeance applicable to melee hits and abilities or only one or the other?
Merciless Combat: Does this apply to Frost abilities or abilities that deal frost damage?
Is Frost Strike considered a spell or not? Will it crit for 300% with Chill of the Grave?
Wandering Plague: Does this cause threat?
What do the diseases of Blood-Caked Blade and Unholy Blight do? Are they unique from other disease and do they also have a DoT effect? Does Unholy Blight cause 120 damage per second, or does it just damage on first hitting a target and simply stack diseases afterwards?
Why would anyone bother getting the following talents:
Will of the Necropolis
Death Rune Mastery
Shadow of Death
Also, I made a Disease talent spec:
War Pirate :: Talent tree Deathknight
The point is dual wielding with fast weapons, Unholy Presence and Icy Talons (30% faster!) to take advantage of blood-caked blade, lots of diseases and boosts to spell damage. It might be better to drop Unholy Blight and Wandering Plague for Imp. Blood Strike. Lots of good AoE fun with Unholy Blight, Corpse Explosion and Wandering Plague, though.
