Should Cassiopea have more of a unique movement benefit? She is half snake after all...

Meddler has already made a post pointing out Cass is a little on the weak end of the mage updates. Overall she lost a lot of early/mid game power in order to keep an overated new W.

Anyway, I was thinking of instead of only buffing her numbers, would a more unique movement mechanic make sense. She is a snake and I feel she should benefit more in movement than her new passive allows.

So...

I think her Q should not interrupt her movements on cast and should have more range.

Also, if a target is poisoned and Cass is not in range for E, upon casting it, she will perform a unique snakelike dash that curves like an "S". This dash will put her in range for her E and can dodge skill shots if timed correctly. it will function a like Ni-dally dash when a target is marked. Once the dash is performed it goes on an internal cooldown.

If she is in range of her E, the dash is not performed.

Would this be op?
