I started playing July 14th 2015, exactly one week after the game has been released. I have over 800+ hours playing this game over the time period of July 14 2015 - June 1 2016.
My first tournament was on July 18th 2015, which is 4 days after I have bought the game. I had 2 other friends playing with me for the 3v3 tournament. The tournament was called, PC Needs Love Too. It was named this because all of the ESL and MLG tournaments were on PlayStation 4. The tournament was massive, there was a round of 128 for just North america, there was also a European bracket as well. Me and my team got to the Round of 32 and got knocked out on July 24th 2015 because we were a new team and have little experience in playing. Fast forward to February 2016 I got into Mock-it and ESL tournaments for PC. Me and my new 2 players won a majority of our games, but never got more than 3 rounds won.
As previously stated above, My first team was back in July and we lost contact after that tournament. In february I got a new team with 2 other players and played a couple ESL tournaments and Mock-it Tournaments. They were not the right fit for me because they were more laid back and standard play, while I was more agressive and trying crazy techniques and I would be the one going for crazy plays. I am currently looking for a team for rocket league that can fit my playstyle and can keep up.
