Team's Response

Result

We are rejecting this bug.

Rationale for rejecting

Our application is made to support multiple competitive games, many of which allow duplicate usernames. As mentioned by the tester, many but not all games have unique usernames. Hence, it does not make sense to prevent duplicate usernames as this would remove support for key competitive games.

Rationale for downgrading

We are downgrading this bug to a low. Even if this is a valid feature flaw, it doesn't cause any hindrance to the user. It gives the user more freedom and doesn't prevent the user from providing their desired inputs.

Evidence

Examples: Brawlstars, Minecraft, CSGO, DOTA, etc
