Duos

Is it just me or is anyone else getting screwed over alot by duos that are just to different of level. playing a G2 game and someone brought in a low silver player. The silver player is adc, and proceeds to play and end game result with a surrender at 20 min is a silver player who is 0-14. and of course our supp then got beat hard too. His duo who was mid does fine then just says whatever at end of game. I really think duos need to be same bracket, or let them play in regulars. every lane won including jungle, but it didnt matter there adc was one shotting us at 15 min.
