I've noticed when I play TFT with a friend of mine who is much better at the game, I lose almost every match. We are similar ranks right now, but he's climbed much higher than me in the past. When I play solo I feel much more likely to top 4, but as soon as we group up I am back to 7th and 8th place every match, while he wins nearly every game.

I was wondering if there was some hidden MMR component to matchmaking in the ranked queue, or if this is all in my head. Anyone have any insights?
