Fuck Discord and their shitty new username system. BRING BACK THE DISCRMINATORS, WE DEMAND IT!
I have no idea why they decided on this system - there's definitely some improvements such as decoupling username and display name, and making the username case insensitive, but unique usernames and prestigious usernames is just such an awful system.
So many things had solved this issue as far back as the early 2000s, but seems everyone is insistent on using it.
I couldn't get a decent username on Discord either, so I just claimed a game name as a meme (pso2ngs) until I can think of something I'd actually want.
