As a Rocket League player with nearly 4000 hours put into the game, I have quite a lot of experience. I have managed to place in the top 3 in LAN tournaments and have played under various orgs. My MMR range is around 1700-1800 so I could definitely help a lot for champion-level and below players. I can take the clips that you provide and review them thoroughly and after some editing, I will happily send then back and hope you learned something.
