Sacred Haven of Debauchery

That's what you think. I always play as Necromancers. And I always win. Well, sometimes I create a half-Necromancer, half-some-other-mage. But I can't do without Necromancy.

I'm also a Necromancer fan, but choosing a Necromancer in D&D-style games makes sense only in these cases:
1) If you're going to take the "Pale Master" prestige class.
2) For role-playing reasons.
The Necromancy school has too many unreliable (or completely useless) spells.
