Yes, she is.
I'm not quite sure how she is rated lower than Luneth, because with that tablet she is insane. And if some some inexplicable reason something survived her first attack, Madness Rush stacks Hyper on top of the tablet.
Completely insane.
Maybe cuz she doesn't have innate dual wield and AoE.
With TMs personally I think she's #1 for now.
Edit: thank you Muku
