Been there. When someone with 10x your kill count (on their single character alone) is in the same game as you. Or the skill difference is evident by how often you are fully armored and are downed in < 1 second from engagement start from some full-auto weapon being fired 100m+ away. SBMM is a great idea, but the algorithms it uses to equate skill are as worthless as the slip/slide and prediction-error-prone servers the game is played on.
Only thing I can think of is that the player count is dying so much that to keep these players from waiting indefinitely to get 60 players at their skill level, they start seeping into lower-level games, where a good time is then had by none.
