They should split it to a low level hide alignment skill and a higher level skill that does the other nifty stuff of "veil of souls." Which, I assume, is stuff like helping vs. conjurer clair spells and paladin track the wicked type stuff.

I've put together at least four different roles depending on hide alignment to carry out my goals, but soloing a thief hidden enough that no one ever sees his/her alignment before I get the skill is some rough stuff.
