I believe that by far these are the players that stood out the most in this tournament, respectively in each role.
Duelist - Demon1
Initiador - cauanzin
Sentinel - Less
Smoke - mindfreak
Flex/Support - Ethan
The most difficult to choose was the Initiator, but I ended up putting cauanzin because among the best teams he was the Main Initiator that brought the most results to his team.
Leo wasn't as good as he was in other tournaments, and the other top teams are basically more flexible when using initiators.
edit : (I didn't put more PRX players because in my opinion what differentiates them is the style of play and not necessarily the individual, save the excesses like mindfreak/f0rseken)
