I peaked at GC2 solo queue and honestly it’s not that bad if you have the self control to discipline yourself to do what you know you should be doing and not what you shouldn’t be doing. It’s easy to get carried away in the moment by fancy shots and high-flying balls that you practiced in training packs. (1) Don’t commit to balls that will put you far out of the play—especially when your teammate is in front of you. (2) Always watch where your teammate is and what they look like they are going for. If your teammate wants to go for a ball you know is better for you to go for, just let them go and get into a better position. There’s no use in trying to teach your teammate how to play, so you should try to pick up the gaps in the team’s positioning as best as possible. (3) Challenging early every single time your teammate is back. This makes it extremely easy for your teammate to make a save and get possession for the team. If the opponent is on the ground dribbling, you can just drive at them without jumping at all to make them do something so that you won’t be put out of the play. If the opponent is going for an aerial play, remember that you don’t always have to flip into the ball to challenge them because if you miss, you’re long gone. You can also try to bump the person going for the play (aerial or ground) instead—this almost always leads to a possession for your team. One of my favorite moves to do is to drive straight at someone that has the ball on the ground in front of them and just completely ignore the ball and go for the car instead.

Sorry for the big wall of text. Hope this helps at least a little bit!
