Rust++ Friend System

Hello Everybody i have just a Short Question and hope you can Help me.

Rust++ has the Friend System. Is there any kind of Benefit if i add someone to my Friend List?

If I remember correct:

Friendly Fire Off = Friends can’t be hurt by your shots.

So if friendly fire is on there is no meaning in adding someone?

when the rustPP.cfg has friendly_fire=false you just can hit each other when both players added in the friends system
edit: you see the hitmarker but no damage

ok thanks im gonna try out
