It was my fault because i lost the game vs 2 cancers

I finally realised that it was my fault because i lost the game vs Diana and Talon before 2 years. I picked Ashe ADC. I'm not sure if i picked Ashe before i saw enemy team, i only know that was imposible to play vs these 2 cancers. Diana just pressed R on me and i'm dead, talon just presses E on me and i'm dead. I just shouldn't pick Ashe. Counter cancer with cancer
