I got 11 correct in the end as well which came as a big surprise to me. I have never watched a single overwatch game and didn't had the will to check some stats. I picked all of them just by the odds. Added few surprises where odds were closer to even. This was probably the MM with least surprises. I don't remember there was ever a situation with this many people on 11+ picks.
Someone in another competition in my local community (just CS:GO) was saying also that all the favorites won in the Asian round of games, and now some of them are being investigated (even though they were favourites),,, because some guy won big by picking all the right picks, so organizers are not happy.
Seems esports is harder to have fair games!
