Well, I like that they get Astral and Death. Kinda disappointed in their mage quality, but it could be worse.
The main plus for me is the idea that I get Death magic, a Growth scale, and access to Blood magic. That's just really nice, as a set. I don't think anyone can do Undead-patrolled Blood hunting like BE Ermor.
They don't get cheap communicants, but OTOH they all get Nether spells, which are powerful, and with a large enough communion, they can all apostacize.
