When I was still playing TF2 in the competitive scene about 7-8 years ago, I played against one team with my team at the time.
They scored 3 wins and 1 Tie out of 5 games; If I am remembering correctly, they later went on to win the season with what I think was 17 wins and 8 Tie's. Can't remember how many games were played in the player organised season. They were a good team with some really nice players, although their Solider player which was their highest damage dealer over the season was super toxic, not even their own team liked him very much and they switched him out after the season ended. Out of the 6 players on their team only 1 guy objected to kicking him, but that guy was rather new to the team so he was over ruled. At any rate if you're a toxic gamer even your team mates will eventually get sick of your shit.
FYI my main class was the Medic or Spy. (Also haven't played in about 5 years either, still love the game and its memes though.)
Thanks
