I believe you should develop guilds so you don't hit your team mates and could talk in a private party chat like /is teamchat is skyblock. This would be great because you can talk to your whole team at the same time without private messaging each individual. Not hitting your team mates would be amazing because, you get so frustrated accidently killing your team mates in diamond and you lose the huge diamond battle in the end.
Thank you for your time!
