As of right now I'm a N/Me, specializing in blood magic and domination magic, with a hint of inspiration for energy-stealing purposes.
Blood: 12 (11 +1)
Domination: 12
Inspiration: 8
Inspiration might be 7, I can't remember right now. Anyway, I works well in PvE, with life transfer and life siphon brining a -10 health degeneration (and regeneration on me), they go down quicker, and the domination magic skills to shut down casters/damage, it's not too bad. I enjoy it quite a bit. Now I head into PvP, and...not so. Even with a -10 health regen and several vampiric gazes cast on someone, I can't seem to bring them down. I have hope if I get a backfire in on a caster while he's got a -10 health degeneration, but I still don't seem to be doing a whole lot.
But here's the thing, I cast a -10 health degeneration on someone and they start to freak, and usually I get the whole opposing team knocking the crap out of me. And believe it or not, ether feast doesn't cover that damage, and with low armor (well not low, 70, but still), I still drop insanely fast. I can't effectively heal myself/dehex all the hexes I get screwed with, and I only manage to take down usually 70% of someone's health, my PvP team just...always seems to lose, and I seem to suck.
==========================================
Now here's perhaps a better question, is it so much that I suck, or is it maybe that my team isn't complimenting my work? I'm not supposed to be the one taking people down right? I'm just supposed to assist in doing it and screw with them as much as I can before I go down. Taking down 70% of someone's life doesn't seem like I'm doing bad by any means, I can just never finish 'em off usually, and then they get healed and I'm without the energy to do it again.
So I've got this question, do I suck? Or is it just that my team isn't helping as they should or something?
Either way, they're my guild and I love the guys so I won't just ditch 'em and get better peoples, because they're all pretty good in themselves, just new to PvP me thinks.
How can I be of more use in PvP 'eh? I've even gone so far as to consider changing my secondary.

I was thinking a N/W. How is a N/W in PvP? Perhaps pump up axe or sword mastery in place of domination, and then...tactics, in place of inspiration or something?
Also I like the idea of my necro with a badass lookin' axe.
Anyways, any build/suggestions and/or secondary changes? What necros seem to screw YOU up in PvP?
---Another note, or, question rather.
When changing a secondary profession, you lose all your original secondary skills 'eh? Well how do you then GAIN new secondary skills? Do you have to go out and buy all of them using skill points? And can you get as many as you could with your original secondary? ---Thanks for your respones people, I appreciate it.
