Need help with my Me/Nec

Hi all, I'm having some woes with my Me/Nec.
I'm using Domination and Inspiration on my Mesmer side.
I'm having troubles deciding between Curses or Blood Magic on my Necro side however.
I was originally going to go for Soul Leech as my Elite for the anti-caster stuff, along with the other skill(can't remember name)that does damage when they cast as well.
I'm wondering if I should take along some curses that do Shadow Damage to the foe whenever they attack(Seeing as shadow damage ignores armor and magical protection of all sorts).
There are 2 really nice ones that I could stack to really take out enemy mobs.
The build will be PvE based which I hope to take into PvP later on.
Any insight is much appreciated.
Also, how many points should I put into Fast Casting.

Thanks in advance,

Mind

Since this build is going to be PvE based, you might want to switch over to illusionary magic? That's what I did and I found I had no trouble dealing with any 1 single enemy using conjure phantasm, phantom pain and life siphon. As for keeping yourself healthy I took blood magic and use vampiric gaze seeing as you do not want to come close to half these monsters. Consider also taking a well of blood and blood ritual to help out. As for an elite I would probably suggest life transfer. It works quite nicely in PvE and this way, you can be degening 1 creature with life transfer and another with your other degen skill while your henchies/team-mates take care of the rest.

The other thing about degen magic in PvE is that you can cast it and run away if your in trouble. So just life siphon right before you begin to run.
