I am severely against this idea - There are multiple reasons why this will not be added:
- Abuse: Players will abuse it, there is no doubt about that. This will lead to confusion both from the player-side and the moderation-side - players will be confused of who is who, and moderators will find it extremely difficult to complete reports, as the only way we can really use this is by knowing a timestamp when the screenshot was taken, then checking a database for name changes, and output who is nicked. This will require lots of backend work, which may take a while to complete, for something that can be so easily avoided by simply not adding it.
- Targeting issues: Sure, players get targeted. That happens to me too, but that sometimes is a strategy - target the weakest person for some free points, experience (and powerups, such as in SG). On the other hand, Youtubers get targeted purely on the basis that they are a YouTuber. They will get absolutely trampled by viewers, fans and haters alike, so having a nicked name will protect them from other players.
- Lack of incentive: Some players will just use the nick function because “why not, it’s a feature for my rank so I need to use it!”. This will lead to verification mishaps such as friends, ranks and other permissions.
In conclusion, I believe that /nick should remain for Youtubers only, due to their upfront struggles with this issue.
