Re: how to chane my profile name?

Firstly, for players with only a single profile, recent update removed the profile name box from the main menu so there is no longer an option for changing the names.  

Secondly, the names you see on the Arena leaderboard are NOT the actual player's profile names, these are the made up names from a look-up table assigned to each player (it was said to protect individual player identity) so your profile name will never be appearing on the leaderboard.
