individual players don't make teams win at even the upper IM level. A lot of the time it goes to whoever puts in the most work and most constructive work as a team. of course having a team with such HIGH CALIBER players like mixup in IM would be sketchy but tbh I see a lot of IM teams being able to compete if they step up to the challenge and put in the time.
some teams are just gonna have an easier time than others
