So what exactly are you guys going to do to evelynn?
Lastly, we want to do a large overhaul to her visuals. Evelynn’s theme of a sexy shadow stalker has been very resonant with players, but the execution is well below our current standards.
So what is she going to look like? It sounds like you are keeping the sexy assassin aspect of her, but unfortunately I have no idea what that really means. Is she still going to be a blue skinned babe in a BDSM outfit? I mean despite having an old model and a rough rig, I'm thinking she's sold a number of skins based on her thematic appeal alone.
We also want to answer the question “Who the hell is Evelynn and where does she come from?” Our Worldbuilding team...
I hate to be undiplomatic but your worldbuilding team can go kiss their own butts.
This is a mistake. A big one.
For starters, there's this elephant in the room: chances are that for most people, the story that the worldbuilding team wants to tell isn't the ones the players and her fans have already made up for her. So you are already forcing an unwanted change on the players. That's not good.
Secondly, and I've been trying to hammer this home for awhile but it's clear no one at riot has listened, is that Evelynn doesn't really work as a character in a traditional manner. In the past she's had AD, AP, and tank builds. Her play style isn't really like other assassins and never has been. For the purposes of this debate, she's never had a traditional background either.
Here's what evelynn is, she's a rorschach test as far as her background is. She's an inkblot that the players get to fill out on their own. It's worked for her and I think it'd be a huge mistake to change it. You know how some rules need exceptions? Evelynn definitely needs to be an exception. You know show, don't tell right? I know people want an answer, but this is one of those times you shouldn't give the players what they want, specifically an answer to who or what she is. Her character depends on it.
Evelynn is supposed to be a mystery. Leave it at that.
