Empathy is different yes, but it's not like Zatanna's telepathy isn't mystical in nature either. After recently punking that demon in his own dream realm I'm entirely certain Raven isn't doing any harm here.
Her magic is instantaneous after the spell is cast. She says pots and then they pots. Conversely, Raven has to draw out her spirit and then lunge it forward.
Zatanna was able to summon an audience of Circe and Spectre under her own power. Raven is outclassed.

Dark Raven as in Raven under Trigon's influence. Under his influence her power fluctuates on the upscale and she actually demonstrates powerful magic during these times.
It could also be taken to mean Titans of Tomorrow Raven, her alternate future incarnation that was able to completely drain the United States of emotion or somesuch. Not what I was talking about though.
