I played ranks for the last 10 hours, and during this time I lost 5 4v5 games, 3 of them were obvious rage quits after going like 0/5 top. I understand that these things happen, but 5 in the single day, and each in my team? Thats unbelieveable. Even in Mobile Legends it wasn't so bad. There should at least be some sort of system like Low Priority queue from DotA that separates frequent leavers from normal games.
