I don't have much experience in MP either (just started my first game, heh), but trying different playsyles in SP I have chosen a blood fountain pretender with a good scale. Blood 6 blessing seems to make the daoine sidhe much more effective, try it.
I was discouraged from using a nature blessing because Tuatha mages going berserk at the slightest provocation are really annoying. Glamour or not, they die rather easy when surrounded by the enemy.
On the good side, with such a pretender I have lots of money to raise a force of daoine sidhe. Order 3, productivity 2, growth 1, luck 1, magic 1, a Dark Citadel for a castle if I remember it correctly.
On the bad side, it's really difficult to cast any high-level ritual spells in the lategame this way, especially nature ones.
