Not to mention faith as well, since with Faith you can give your allies Buffs such as prayer which is a +5 mana buff, or Blessing with is a +10 vit buff, even if you take a -10 in turn.

Or the up there stuff like anoint champion or shoulder burden, even removing Age DR for a year, it even unlocks holy magic for you, i think.

Between Necromancy and Faith, there's little reason to ever go for witchcraft because you don't get much from it other than having to live a more dangerous life. It's like outlaw but you're more likely to die because of it. At least with outlaw you'll maybe be permed every now and then but usually there's no outright reason to take you out.

It doesn’t unlock holy magic…

It does however open the door wide open to developing it. However I don't think thats really an argument of faith VS witchery because witchery does the same with occult. It doesn't unlock occultism but it certainly makes deving it easier.

But once again I personally know nothing of faith so faith is not really part of my discussion. I can't speak of it, I'm too unexperienced.
