Blackrock suggestion: Hide your location on the friendlist

Since the Blackrock realm focuses mainly on PvP competition, I’d like to propose adding an anti dodge/snipe feature.
Just a simple option to hide your location after entering the command.
Specifically, for high mmr players, there could be an option to lock your status on the friends list, so that it always displays as if the player is in Dalaran.

High rated gameplay tends to be quite hermetic. Not knowing exactly who you’re facing would create a healthier balance and make it harder for players to abuse.

I'm an absolute pvp noob, and yet I'm still able to understand how great this suggestion is!
I sometime spectate matchs, and it's crystal clear and there is sniping all around...

A simple fix to resolve a huge part of the issue!
