Yeah, to me, Abjurer has so much more potential simply because of Superbeast. His skills have no CD, they're essentially procs, so having 4 target point singularities, and the screen covered in lightning novas and lightning waffles, is pure eyecandy. Not only that, but his DPS in superbeast is just insane. Even with mediocre gear, he's strong. But if you stack enough buff duration for almost permabeast, it's damn well gamebreaking.
Not only that, but those mages are pro af at skillswitching haha, zero human error. They can bust out some crazy multi-element spell barrages.
