I believe the Vulpera can be Warlocks and Mages because of their overall theme. They are extremely crafty and quick learners to be able to survive and thrive, they likely picked up on the tricks of Alliance magic users coming into their zone and burning their stuff down every few days for months on end.
I imagine in a more in-depth look at them their mages are less refined and more on the line of “Oooh what does this do!? WOW, that was GREAT, ill have to remember that one!”
