As riot stated on This post They will work on other 2 more champion specific Eternals for all the characters. Most of us felt sad or disappointed on how wrong was riot with the champion specific eternals that they made by themselves.

For example the Eternal that they made for Zoe is " Rude Awakenings: Enemy champions killed within 3 seconds of being slept by Sleepy Trouble Bubble (E) " it's a cool Eternal, But I'd prefer something like the units that my Qs have travelled in total, or Times I've used the summoners of my enemies against them.

I thought it would be cool if everyone said what Eternal would we like to see for our mains, this is not a post to do Riots work, but more like a post to give advices so they don't fuck up while trying to make extra eternals for our characters.
