She heals en-masse *over time*; this is why she is bad at doing damage in small trades but does reasonably well at dealing damage in big trades or all-ins. If she kills something before the healing can ramp up, or Qs it during the trade to mitigate the healing, her healing passive doesn't really come into play.

Indeed, though, she is actively punished for misplaying.

Also, RE: her ult, at rank 1 it's a 0.75-second 40% slow. If she ults, say, top lane, she'll prevent maybe one autoattack and allow her laner to land one extra auto; any other global ult would've had a bigger impact on an all-in. It's decent at allowing a disengage or stopping a turret dive, though, since it offers more healing to the losing party (% missing health).

Even at max rank, it's 1.25 seconds of total CC and 0 damage unless she's present to press Q. In a pinch, it can maybe turn a close fight, but, again, it's hands-down the worst of the global ults in most cases unless she's around to press Q.

Also, her displacements are about the intensity of a Vi Q (with no damage; they actually heal, instead), 2 of them hinder her own movement and 1 of them effectively stuns her.
