MM doesn't even feel fair at this point.
I've been at the highest mmr or nearly highest mmr (assuming that's what decides captain pick and 2nd/3rd slot) in my lobby for about 5 games now and that hinders me because they get the perfect chances to counter me in whatever I pick. I get placed into a low ELO 2 seasons in a row at 8-2 placements (last season I was like 7-3 or something) and I'm literally forced to choose the one role that doesn't really get countered (support) in lieu of a champion I can better affect the game in. Since this is low elo, surrenders rarely happen either so it doesn't matter if I feed my adc with ease; if they outscale us anyway or our fed adc starts derping, it's over.
I did try picking someone with few counters and I got countered by one of the most strongest champs this season...Graves top vs me as Nasus. I rarely lose Nasus games but that was cancer, as is any game with Graves in it.
It shows in the people I play with unfortunately. I lost like 5 in a row after winning nearly 6 times in a row to get to promos, losing promos even with promo helper. Doesn't matter how well I play. If our damage dealers are derps that attack Nautilus instead of Lucian or never listen to pings and die 20 times, it's practically always gg.
