Luck doth matter -- a lot.
A Devourer of Souls build, for instance, is all about luck. If he hits the right target fast, he wins... but that's far from guaranteed, and the lack of slots hurts his long-term life expectancy. Gifts from Heaven is similar... *if* it hits, it hurts.
Incidentally, if Phoenix Pyre actually worked well for multi-shape units, I would have considered going with a Phoenix Pyre'd Daughter of Typhon, just for amusement value. But some testing suggests that the reappearance is lost once you lose a form.
