Hello!
The menacing scowl has been a customization option for male Night Elves since the launch of World of Warcraft. Back in the Warlords of Draenor expansion, the Night Elves had their character models updated and that’s when we updated the 3 menacing scowl faces to be the somewhat less menacing faces that you see today.
We looked into the number of male Night Elves that players have created with those faces and we found that they aren’t as popular as the other face selections. We agreed with your feedback that having 3 of the 9 faces with the scowling mouth may be hindering your face options, so we have copied these scowling faces and added a more natural posed mouth as 3 new face options for you to choose from in Eternity’s End.
We understand that there’s a long history with these male Night Elf faces, so we would love to know what you think. To help visualize the changes, the three new face options should be available for testing in this week’s PTR build.
