The class least likely to be added?

Or they could use a design that is okay for all regions?

Necro is part of the name >_> tell me how they could design it where there would be nothing associated with the dead because any perversion or desecration of the dead is a huge taboo to their culture, their version does not have skeletons and zombies for this reason. I highly doubt SE would bother designing 2 sets of animations for 1 job that is more work than necessary compared to other options like a single job that is fine in every region.
