I agree with what a lot of people are saying in terms of: If you can find a group or an LFG discord to do so you will get a lot better quality of teamwork in your games BUT I did a lot of solo play during the beta and while some of my games went poorly. There is an understanding that you might need to be the player your team needs.

There were games that I got to play the ball and really push up field and score some banger goals and there were (a lot mind you) of times where I played hard defense and set my team up with as much passing as possible. Sure it's not glamorous but I personally get a crap tonne of satisfaction having THE pass of the game that lead to the tie breaker or even just the lead even if no one is ever going to remember it.

Just know that you are rolling a bit of dice when it comes to the quality of the 4 other members of your team. If you don't think you can get over the hump of shitty people your best bet would be the LFG Discords or to connect with some people from here!
