Aside from the state of Elise's balance, I think her passive should replace damaged spiderlings
Lets say she has 5 spiderlings alive but all have low health, when she turns human her passive should replace one of them for each time she hits a target with an ability.
Unfortunately when she enters spider form again those spiderlings health remain low and they become extremely vulnerable.
If her passive did replace them however, It would technically be a buff even though Its something that I feel was overlooked and should be a part of her kit.
I currently find myself trying to sacrifice low health spiderlings in order to replace them with full health ones via human form, but there is usually no time when it counts.
like I said It would be a small buff but it's a mechanic meant to be part of her kit.
