I know devs have way more important stuff to keep up, but could it be an option to transmog cost bronze/silver/gold instead of fashion coins? Fashion coins still could be bought in the donation shop(if one exists again) for people who don't want to spend in-game currency. The Twow Transmog System was kinda hard for new players to engage with and have fun with this system.
I am aware that those fashion coins were dropping regularly in endgame instances, but both coins are tied to the character, and in the case of a player like me who's not interested in endgame content, i just make another alt character after reaching 60. I would love to see the fashion being money sink, either that or fashion coins being made account-wide to encourage people doing endgame instances for their alt characters.
