Joining randoms. You can join voice channel and talk (some people do, some don't) and there is also a ping system where you can tag enemies, mark locations and where you are going, etc and your character says "Going here" and if a team mate tags you can confirm and your character will say "Yep" or "Alright" or something like that. I've had a bunch of wins playing with randoms without even talking. I think I'm at about 25 wins from 85 odd matches. Pretty much all Quick cash. Doesn't sound like a lot but decent enough I thought.
