While I love the changes to her stun and it will boost her early game extremely, Riot has yet to touch the parts of her kit that actually needs buffing. Her Qs. They need to boost the base damage and the addition % health damage slightly. They also need to move her Rappel buffs to her Skittering Frenzy.
I also believe she should be able to store up to 2 Volatile Spiderlings too, but that may be too much. I also wanted to suggest that her spiderlings explode upon dying (like her human W), but that may be a bit too much.
