6v6 Team Fortress 2 has existed for about as long as TF2 itself. Since its genesis, generations of players have taken the knowledge and skills form the players before and built on top of it. Over years this has led to a very optimized metagame, but the question remains: how optimized is competitive TF2 actually? #tf2gameplay #gaming #competitivegaming #teamfortress2gameplay #teamfortress2
