I think the thing which could make or break the champion's gameflow is that cooldown on W for unattaching, combined with just how necessary her passive is.

For example if the cooldown for unattaching is trivial she'd be able to hop around people at will, jump off to proc passive then back on whenever, but if it's quite long it'll open up some large windows for her to be attacked (I'm expecting sub-sona levels of squishiness to make up for being untargetable for most of the time).

And if she has has high mana regen and a good pool then proccing the passive become less important anyway. But if she has literally 0 mana regen and relies entirely on her passive to keep her casting then again that will be times when she has to make herself vulnerable.
