So these Elise buffs slated on the PBE are kinda good
Venomous Bite (Spider Q) damage increased from 60/100/140/180/220 to 70/110/150/190/230 Cocoon (Human E) cooldown lowered from 14/13/12/11/10 to 12/11.5/11/10.5/10
Unless you're in a drawn out fight it's unlikely early game that you'll be using E twice or human form Q twice. Granted I max E first on Elise Mid game the change can be really noticeable because you can throw out cocoons more often. The Q change is pretty whatever. Elise could really benefit from a small rework like changing one of her abilities or something.
I predict that if these buffs go through Elise will see a 0.8% winrate increase. Getting picks with E mid-game could really give her a boost but in comparison to other junglers it's whatever
