I started playing over watch 1 the season that sigma was released. So I'm not one of the OG players, but I think it's fair to say I've been around a while. a lot of people get mad at all the tweaking an rebalancing this game gets. I personally like that the devs are always trying to mix up the game, it helps keep the meta from getting too stale. some people are just too hardcore about playing one specific way.
I also do enjoy the change to 5v5. if you played and enjoyed the game at some point and now you HATE it because they nerfed Pharah's rockets or whatever, just get over it. learn a new character and have fun with it.
this is a good game worth a try.
