looking for some advice from dedicated riven jungles!

so i played a few normals, they all went incredibly well, but its also normals. the clear is as easy as it gets (i can auto cancel like 75% well not fastest possible, but decently)

the clear is similar to graves health wise, full clear on average in around 4 minutes. The biggest issue i ran into - ganks.

Laner positioning is always mediocre at best, a lot of junglers can make work of it anyways do to engage potential, but here i come e, q, q, ing in, they have plenty of reaction time, giving my flash makes a perfect gank but only every 300 seconds.

Any tips and tricks to be offered? im pretty sure riven jungle has a niche somewhere, i see potential.
