If local voice comms isn't possible at least some form of comms. I have been playing captain a lot lately and often I have seen the enemy team coming in for a flank and I can't tell my allies anything to warn them quick enough. It's mega frustrating. There is no point in adding voice chat just for groups. If you're in a group with your friends, your probably going to just use discord. But for playing with other people you need some form of comms.
