Flex Queue Matchmaking

Me and a friend of mine went duo into flexQ. The enemy team was premade of 5 with a really strong team-comp (kog, lulu, zilean, malph, nunu). I was jungler (Elise) and I knew that we had to win the early game in order to win (that's why i picked strong early game ganker). I kept ganking, successfully, I kept telling them exactly what to do, but the 3 random people in our team just wouldn't listen and kept doing exactly what the enemy team wanted them to do. The enemy team, 5 people premade, were really well coordinated and it was visible they don't play that team comp for the first time. Even though they were just a bunch of silvers and golds, they've won.

I feel like there was absolutely nothing I could do to change the outcome. They obviously practiced that team comp and were using some voice communication program. Despite knowing the counter play, it was practically impossible to perform it.

In my opinion a duo should NEVER be matched against premade of 5 people (especially in this meta of bot lanes having huge impact).
