You mean that she's going to be toxic as a jungler with her R being available before 6. The scaling on her new E(R) isn't all that different from what It was as an R, so it's probably going to be broken as a soon as a Diana gets her Echo in jungle. It's also going to massively increase her already good clear speed, since E (R) can be used on camps to double E.
The only thing that was keeping her from being toxic was the fact her old W used to be an almost non effect no damage skill. Now it's on her R, and does damage as well, and massively pulls a larger area.
Now.... she can Dash at level 2. Think about how that changes her jungle profile, and not only once; she can dash twice.
