The game has a steep learning curve. If you are willing to learn how to master the game, people will likely be kind to you, but be prepared to encounter quitters, ragers... and some kind people.
A good teamplay is rare because most people dont like to defend, they all want to score, while a good defender can be man of the match over someone that scores 5 goals. Its of the essence to play the role that is given you the best you can or switch with someone that is willing to change position.
The Goalkeeper AI is bad most of the time, and there are many ways to take advantage of that.
The gameplay is just fun, it takes some time to master the controls and know how the different statistics work on your performance, ones you get the hang of it and find a good party or PMC, things get more interesting than going in random matches.
I would recommend this game to people, purely for the game and the fun you can have with it but dont let the fun be spoiled by anyone!.
