With Ul'Dah I get that they would publicly decry any form of Necromancy but possibly endorse it behind closed doors if furthered their goals, basically something as the WoL that cannot happen because we are so public when going about our business, hence the very thin line Necromancer would have to tread in Ul'Dah.
