Demon hunters, mages, shamans, and warlocks all use some variation of blue and purple. On that page you can see that shaman and mage are clearly quite blue compared to warlock and demon hunter.
Though yes, our modified color scheme is a tad less blue than the default shaman color, I’d say that it is definitely still pretty blue, and not nearly as purple as warlocks.
