Why isn't there a mute button?

I’m surprised not many people have been talking about this. If there’s someone I don’t wanna hear during multiplayer match, I can’t mute them using the leaderboard like previous games. The only way to mute them is to go to settings and disable game chat but that mutes EVERYONE. That is so stupid, why would they not include that? What if I’m talking to a friend but there’s also an annoying dude talking and I want to mute only him? I can’t. I would have to mute both my friend and the annoying guy.

I hope this is just a beta issue and it’s NOT like this for launch.
