I'm not a fan of the name either, unless it has snake or poison themes (which should've been shown in the reveal if it has any). If anything, it sounds more like a title or rank, rather than a class/job - kinda like how the reapers in Ul'dah are the Lemures, but you don't see the job itself being called Lemure.

That said, it's already been revealed, so unless the overwhelming majority of the playerbase disaprove of the name, they ain't changing it.
