At this point in the process, it's better to overtune with the first draft and gradually find a sweet spot per reduction, because the passive is undertuned in terms of performance.

As per her problems:
 * Twin Fang health sustain only becomes a problem in the late game, and I was to nerf the scaling of the mana restoration (Base cost, from base + 3% of Maximum) as a compensatory measure.
 * Increasing the range on Petrifying Gaze would push Cassiopeia over the top in terms of teamfighting performance. If anything, changing how it's calculated (Edge to edge instead of center to center) might give her a QoL fix, but the wind-up is a source of counterplay that Riot simply wouldn't take away for free.
 * She's not getting a dash, blink, or non-ult CC on her kit as it stands now, and we all know this to be true. She might have to work for mobility harder than other champions who can point click, but the point is to give greater sustained mobility over time in exchange for being vulnerable to gap closers.
 * Cassiopeia on Live, Cassiopeia on PBE, and this Cassiopeia all have that attribute in their kit: she is weaker early than she is late, and she needs to combo her skills to get the most out of her kit. So why not reward players who are able to combo consistently?
 * Within the power budget, you either improve the AP ratios or you remove parts off the passive. That's the balancing tool they want to use. When I get back to redrawing her, I'll fiddle with ratios.

And now my question to you all:
 * What parts of the passive do you find rewarding? What would you change, keep, or swap around?
