If you would compound a team, of which the players are only maining a specific role- who of them would win?
For example, a team full of support-mains facing off another team of jungle-mains, who has the higher chance of winning? Maybe the supports because of better gamesense, or the junglers because of better shotcalling? (I know, rough example, but still).
My choice goes to ADC-mains, since it's the most difficult to play mechanically and the most intense in terms of working with your team.
Would be interesting to see what the general opinion on that is.
