Making Elise stronger again, add damage amp on her cocoon
With the upcoming changes to Elise her Q, Riot is attempting to make her a bit more viable and stronger in the new jungle for the next season. While she will benefit from these changes, Elise will still scale fairly underwhelming into the late game if you build her as a utility tank (standardized build in current meta).
I'd suggest adding damage to her Cocoon (E). Most champions with CC skillshots have a damage multiplier but Elise hasn't. Like Xerath, Jayce, Ahri but Nidalee would be the best comparison in terms of gameplay and skillset.
Why not add similar damage per level (20\40\60\80\100) and perhaps a little something extra like a percentage damage based on enemy health over the duration of the stun (10/12/14/16/18% +1% per 50AP).
Other transform champions such as Nidalee, Jayce and Gnar all have some form of damage amplifiers on their respective skills but Elise hasn't. With the ever changing meta sure Elise is still in a healthy spot but it has declined with every patch release.
I hope you guys take this into consideration for future patches
