If you play ranked without op.gg'ing your team...

... then you're shooting yourself in the foot.

My smurf is between G1 and P3 right now and my team had a 35% winrate G3 player and a 50% winrate G5 player on it. They were both in their main roles playing champs they have not played with in the last 2 seasons. Had to dodge.

Next time you get crushed (and it's not your fault), try looking at the op.gg for the match and ask yourself: could I have predicted this?
