It used to be like that, but they've changed it... now it doesn't matter what division you're in, you always play against people of your own level.
I'm a player who gets between 12 and 14 wins in FUT Champions, sometimes a few less depending on my connection, which is usually terrible. I'm in Division 6 because I hardly ever play Rivals.The point is that in that division I'm finding people of my level in EVERY MATCH, which is impossible unless there's a skill-based matchmaking system.
To that we must add that each match search takes between 20 seconds and 1 minute, sometimes it even says "no opponent found" which is further proof that there is something strange about the game.
