Way too much things be granted with that passive.

The problems that she has are the following.

If from your intentions (And those of Riot) there is something worth to rescue, is the following:
 * Twin Fang grants too much sustain, as it grants high-scaling health and mana restoration. Yes, is nice for the user, but too frustrating for the opponent.
 * Petrifying Gaze's wind-up before cast, aswell as the short range.
 * The bonus movement speed isn't enough to free herself from champions with mobility.
 * Despite it is, in fact, nice to gain those pretty stats from the innate passive.
 * Having to stack it may be a problem, because being shutted down in the laning phase is even more punishing, as would lead to her not having an innate passive.
 * In order to compensate the snowball-y passive --specially due to the free stats, rather than the heal-- her AP Ratios were gutted.
 * Despite the otherwise intended utility of the innate passive (Still gain the desired amount of stats and be able to build herself tanky, since she's a close combat mage), players still need to amass AP in order to deal damage, leading to her being soft and squishy.


 * Changing her kit without destroying the identity of her current one (At least the active part of it, that is).
 * Damage amplification against poisoned targets (Rather than bonus AP in exchange of nerfing AP ratios).
 * Mana cost reduction per subsequent casts (Rather than monstruos mana sustain).
 * Leave her health sustain.
 * Buff her ratios.
 * Fix her kiting against champions with mobility (Without giving her mobility beyond the bonus MS).
