Adding four random digits to people's names was a brilliant solution to two common problems with usernames (users wanting the same username and usernames of notable personalities getting leaked), and now they're just going to the exact same system everyone else uses with all of its attendant problems? Fuck off
Normal usernames people are used to: case-insensitive alphanumeric string with maybe a couple of hand-picked special characters
Discord usernames: case-sensitive alphanumeric string with any number of special characters and a randomly generated code at the end which is typically never displayed
Sorry but you're just wrong on this, denying it is like denying the grass is green lol
Have widely-noted problems
Solves many of those problems
Even if they are more complicated than the industry standard your continued insistence that they are "extremely" complicated is incoherent to me. Discord is making this change because every tech company reaches a point where their growth slows down and in order to chase their old growth numbers they start fucking with systems that work, and at best come up with something that is equally good but more often than not come up with something worse and the userbase is stuck going along with it.
But they've explained exactly why they don't think the system they're fucking with works well. This isn't just a case of changing stuff to change stuff, they're changing something which is problematic to address those problems.
Also notice how at first you were like "they're not more complicated" and now you're like "ok they are more complicated but it's worth it"
Discord doesn't think it's worth it. It's as simple as that. Now you understand what they were thinking. But keep moving the goalposts.
I've never denied this. I've only said that I do think it's worth it, and that I find Discord's explanation lacking.
