I suggest this because the time i went for a tournament last year, the headset used did not block out all the noise of the gaming room and communications between my teammates were just hard to hear. Also for tournaments in any game, Can the random free agent people NOT be put up against premade teams that already know each other? putting up a team that already know each other against a rag tag group of randos is not how you should run a tournament. game in question is Overwatch btw but this is just a suggestion.
