Games starting without teammates

Sometimes it happens to me as well. Either 1 teammate is missing, or I am just straight up sent in alone. I have no choice but to camp in some dark corner near the ring. I actually won a game that way once. Was alone right at the start, camped in a corner. No kills, no damage, haven't seen anyone, and all of a sudden, you're the champion 🙂 

Ok but that was just 1 game. All the others I died at some point.
