I won a 4v6 once. Enemy team had 5 DPS and 1 tank. My team was all on mic and a good comp for a 4 man. It was bronze tho but still glorious to pull out a W
One time my whole team left so the other team let me cap 1 point and lead me to lther they wouldnt let me capped i ulted i was junk and killed 3 of em and killed the rest and i won this was on qp sadly not comp
I know the feeling this has happened to me more than I can count holy hell. It sucks but if everyone has mics and communicate you should be okay but you are handicapped because you are short a man.
