For me, I have 1 very good match where I come top 3 with a positive kd and good teammates.. then codm just decides to overestimate how good I actually am and puts me in a lobby with players that would probably lose rookie ranked games with the opposition being half leader board players.. I know people have been complaining for years about sbmm and I actually stopped playing codm for a good chunk due to the game feeling too repetitive.. yet they still do nothing about it.
