Not sure how to word the title properly. I truly hope that the people at Discord company will refrain from interfering with the current system that we have (discriminators), because it works as is and prevents being found easily. Was this not supposed to be what would the future be like? Insolent company dares to try to do this change. Are you going to consider what kind of clean up you will have to do? Are you going to consider Nitro users as well? Having a custom tag was a kind of Nitro addition, are you telling me you would be removing a feature just to accomodate for this one?
If I could I would try to see if we could speak with someone at Discord and ask if they really do like the change that they want to do or if it's just because of investors being investors. Nobody asked for the change to happen. I truly hope the backlash will make you reconsider, since you've already reconsidered a few other stuff (like the reply thing on mobile).
