If you have a mic and decide not to use it besides when you/team dies to flame and talk shit then what is the point?

Literally got out of a game where two of were using our mics to call out comms and our third just said silent the whole game. We get pinched from behind without knowing that we were getting pushed even though our third was at a different angle and saw everything. We both get knocked and this guy finally turns on his mic to say that we are dog shit and hate having teammates that get knocked so fast. It made me quite waiting to play for the rest of the day.

Tl;Dr, If you have a mic please use it for comms, atleast when you flames us for being shit we are fully awake of whats going on ahahahaha
