The advantage of Regen for a Necro is MASSIVE. Anyone who has played both an iksar and non-iksar will tell you its night and day, literally.
If you plan on going all the way to 60, do yourself a huge favour and re-roll.
If you need proof you should search the forums (specifically the Caster forums) for any posts about Race choice for a necro and heed Sesserdrix's words. His posts will sway your decision and you will not regret it
