Pros and cons about this W/N build

I haven't decided attributes yet but....
Vampiric Touch
Vampiric gaze
Final thrust
power attack
gash
sever artery
hundred blades
savage slash

Any pro/ cons aobut this build? any good replacement skills?

Well the pro's would be you have way more armor than a N/W...but less energy...N/W's have a base of 30 energy, which might be better if your planing on using a lot of energy skills, but if your focus is on warrior skills then W/N might be better..Though Vampiric Touch costs 15 energy I think, which would leave a W/N with about 5 energy left, and a warriors energy regen is sloooow..so don't really expect to be able to spam Vampiric Touch/gaze a lot.

In a Warrior/Necromancer I'd assume you'd run only one health steal spell, preferaly one that acts at a distance to give your warrior some versatility, and a slew of other warrior-related attacking spells, possibly complimented by a Signet for healing or something necro-related for healing. Other than that, I wouldn't bother with much more, given your lack of energy.
