The Necromancer Class would be available to all races except NightElves and Tauren.

The Necromancer would have ten minute control over a fallen enemy's body and use it as you would a pet/demon. The 'controlled' enemy would have stats of an undead for that period of time. Could you imagine the FUN of seeing a controlled enemy EAT it's friends without being able to stop itself? *cackles evily*

Also, if a member of their party or ally falls in combat or say a battleground , the Necromancers have a spell which is similiar to the ressurection spell but with a twist. You can click 'accept' when you die to be used by your allied Necromancer for ten minutes. This is great if you are killing a Boss or your gy is too far away and you really don't want to miss out on the fight no matter how restricted you may be.

The Necromancer himself will have spells naturally and like a Mage be able to use a sword / staff / knife. However, knife / dagger will be his favoured weapon as it accompanies certain spells / rituals such as 'create undead'. For every ten levels perhaps a greater blade is required and so forth, which can only be aquired through fun yet difficult quests pertaining to level. Such as Warlocks go through to get their next demon and so forth.

They use mana but for certain spells like 'Create undead' they must have their 'soulbar' atleast half way. They fill this up by consuming souls from the dead not the living, in contrast to Warlocks. The body must be sucked upon the moment they die to gain the required energy.

The Necromancers would worship their own Master, from where their Knowledge stems from and though most races dislike Necromancers greatly they realise that they are a necessary evil to have on their side with the hopes of destroying their class afterward. Yet Necromancers desire power and will do whatever, promise whatever to achieve that. Starter robes are hooded and black so as to protect them from sunlight. This is fun as most races have no headgear early on. But from Apprentice stage, a Necromancer will be able to use their hood at will.

Spell examples:
Clutch of Panic - Enemy's Stamina is reduced by 50% for ten seconds
Clutch of Frenzy - Enemy's pet / demon turns rabid for ten seconds and turns on their Master
A.O.E - Maggot Insurgence - maggots appear on ground (like those in Plaguelands) and attack nearby targets.

Weaknesses:
Light obviously!
Cloth wearers so minimal armour.
