I'd rather them just A) remove the buff or B) move it to skittering frenzy even with lower values.
Putting the debuff on her cocoon (which I believe is the only hard CC ability that doesn't deal damage in the game besides rammus's taunt and terrain from anivia/taliyah/trundle) kinda makes it a waste to have since you're partially in human form where your passive isn't available in, and weaving in venomous bite delays about a second of it too.
I'd rather them remove it so they can add additional power else where.. maybe even replace the buff entirely for; elise refreshes all her spiderlings when she descends and respawns her max cap back. Its kinda pointless to have unless you're 10HP and want to get greedy for a jungle camp and those situations are often rare for a champ like her unless she barely lives a tower dive and wants to still farm.
lmao all i want is her to get more attack speed that she never got compensated for from losing runes and machete.. but wukong can get an attack speed buff sure.
