This game desperately needs BETTER proximity voice chat

so, me and some buddies decided to go try the Detatrine missions. We land, we buy the stuff and start loading. We have one person in a ship scouting, an aurora lands nearby and I tell him to not kill it. He is just circling around the guy and the person on the ground is trying to hide.

I get close him and start talking on proximity chat, but he does not respond. I could've killed him at least 20 times, but decided to be peaceful. Tried to sneak behind him and stun him, so we can talk, but he saw me and killed me, then my friends had to blast him off.

Now if we had a proper system to communicate, this might have been avoided.
