@PeacefulNPC You mean to say that if you have alts with different names, you'll forget the name of the toon you're playing and not be able to say it in voice chat?
And about discord servers, you can just change your nickname before a raid to the name of the alt you'll be playing, it literally takes 5 seconds. Alternatively, you can just put all your alts' names separated with slashes if you're lazy.
This change wouls create WAY more problems than it would "solve", and there are alternate aolutions to your problems. Please don't allow accented characters in names.
