Drop the blood magic down to 3/4.
Max curses, rest in soul. Bring [skill]Blood Ritual[/skill], no other blood skills - the rest are pretty terrible. Take out siphon, gaze and lifebane strike for [skill]Price Of Failure[/skill], [skill]Reckless Haste[/skill] and [skill]Desecrate Enchantments[/skill] or Defile, or Barbs.
Drop the hard res for a res sig, go /Me - and bring Arcane Echo, and that's your standard SS build (in before blahblahblah wiki builds omg innovation etc.) it works, and it works well.
If you prefer running blood, swap the points around a little, max blood, 10 (9+1) soul, rest in curses and bring an elite like [skill]Spoil Victor[/skill]
You've got a good start, but SS at 8 curses is meh.
Is This A Good Build To Go With???
