How come op.gg tells me that my MMR is Silver 5, but I just had a game, with an unranked player playing through his Provisionals. There aren't enough games played through to even give him an MMR, so why is he on my team. And shouldn't the matchmaking be equal on both sides. Giving my team Silver 5 or lower, and the other team has Silver 3's and 4's? I'm confused on how the matchmaking system works.
1 rank =/= MMR. the rank is completely irrelevant for matchmaking, the only thing that matters is the mmr. the mmr and the mmr of the other players in a game determines how many LP you get and lose for that game. a gold 5 player can have the same mmr as a silver 3 player for example.
2 every new ranked account starts with a default mmr which is somewhere around mid to low silver, so there is no account without mmr.
3 op.gg just kinda guesses the mmr and in most cases is not accurate.
