Don’t feel pressured to use a mic, you can get through 90% of situations just with the in-game responses (yes, no, sorry, thank you, wait, follow me, I need supplies) by holding the ping button

Also don’t be afraid to use the matchmaking, the game is best in lobbies of four and I can think of only two or three negative experiences I’ve had with randoms in 300+ hours. Leave and find a new one if someone is being an asshole.
