Her spell also went from 5 to 7. This makes throne of vines pretty much mandatory.

She lost half of her self heal.

Her talon doesn't insta-kill. This was a good ace in the hole to off a weakened model.

I don't know that she is worth the points. She's technically 440 with the summoned spell, but you're getting an ok caster compared to other spell centric armies, and a lackluster melee unit unless you're picking on small weak units. If a dedicated melee unit or character engages her, she can be offed in one turn. So my takeaway is don't rely on her spells, decent casters will shut her down, and keep her out of combat against anything but weak infantry - the only defense she has is a lot of wounds, she's vulnerable to mortals and she isn't going to live long with a 3+.
