Have a system in place to allow you to “check pulse” on another player and a scroll wheel to “ask for their trust” and if they accept your invitation, just give them a green dot above their head that is clearly visible but only up to 25m away, or not even 25m away but at least if they are in your line of sight. Would make friendly fire a little easier to deal with as sometimes im running in a group of more than just one person. In real life i know what my friend looks like, but in game he could be standing in front of me and someone else just comes out of nowhere and now i cant differentiate between the 2 of them. This would be a huge quality of life improvement, and if the other player doesn’t want to “trust” then they don’t have to accept the invite.
