Diana Moonlight, R

How come when Diana ults a target afflicted with "Moonlight", it consumes Moonlight on all enemies? Why not only consume on the target she ults to, and allow the effect to stay for the 3s so Diana can dash to multiple targets?

Also something I suggested before, why not make her Dash a crescent moon shape (arc) like her Q, damaging all enemies hit (and consumes Moonlight on all)? Or at least make her dash in the same arc path after applying Moonlight with Q.

Maybe make her passive apply Moonlight when she cleaves? I feel like there should be more Moonlight interaction in her kit.
