Core 7 Skills
[skill]Dark Pact[/skill][skill]Vampiric Gaze[/skill][skill]Shadow Strike[/skill][skill]Offering of Blood[/skill][skill]Signet of Lost Souls[/skill][skill]Dark Escape[/skill][skill]Heart of Shadow[/skill]
Most of these speak for themselves. Shadow Strike and Lost Souls offer two great skills to use depending on if your foe is above or below 50%. Offering is there to keep the energy flowing. Escape/Heart for extra survivability since Dark Pact and Offering both can bring your health down in addition to mob dmg.
Filler Skills
[skill]Awaken The Blood[/skill] Great addition if you can take the 50% sacrifice increase. The boost to all your Blood skills will be great.
[skill]Life Siphon[/skill] Good sustained leech. Nice for those mobs that just won't die.
[skill]Shroud of Distress[/skill] A nice avoidance option.
[skill]Unholy Feast[/skill] AoE leech.
[skill]Touch of Agony[/skill] Could sub this in for Dark Pact if you're going solo and don't mind the range.
[skill]Well of Blood[/skill] Good group addition.
[skill]Plague Touch[/skill] Anti-Condition.
[skill]Mark of Subversion[/skill] Anti-Caster
[skill]Strip Enchantment[/skill] Anti-Enchantment
What do you guys think? I believe this has a pretty strong core of skills to keep the damage/health/energy flowing with enough alternates to deal with most threats if you know what you're going up against(PvE). Does it appear to lack anything in particular? My only concern is Signet of Lost Souls might be a little unnecessary since Offering is in there...the heal is nice though

Thanks!
