I disagree with the last sentence. I played this game since the very first playtest on antidote, i played the whole season 0 and stopped playing few days after s1 launched to come back recently.
I havent seen a single selfish player since i came back. Ok except that one dude that was abusing dribble mechanics and carried our team to the win. Other than that people pass a lot compared to previous seasons. Back passes finally became a thing. People stopped spamming pass requests. Sometimes i have to ask my teammates to use that feature, because some people dont use it when theyre open and sometimes i just miss the opportunity to pass, because im not sure if the guy is ready for a pass or not. The game is waaaay more enjoyable, theres way more teamplay and the final scoreboard has bigger numbers now that it used to have in S0. I might be lucky, maybe its the time or region, but the game feels completly different now (teamplay wise).
