I usually host as party leader from the terminal, and I found other members of the party was able to accept requests of other players to join.
Somebody in the team accepted a player using a class that set us at a disadvantage, and I ended up demoted.
Is there any way to prevent other players doing this?
Yes: write or say something in group.
I’m obviously asking if there’s a way to disable it
nope, gotta ask the guy to leave. if he doesn’t you have to either play with him or leave the party and restart the process
I think FatShark should change this. If I host my party I want to be the leader and manage it, otherwise I might as well play quickplay.
