I didn't play too much in the beta, only a few rounds a couple months back. Started playing last night and man is this game fun. Haven't had this much fun playing shooters since the days of Day of Defeat and TFC.
I've got the Origins Edition, which I bought instead of the basic one because of the Hearthstone cardback (lol). I'm still low level, only level 5 yet. I'm playing mostly with the Soldier guy, he feels like the Jim Raynor version of Overwatch. I've already got the "play of the game" multiple times thanks to his ulti.
Don't watch to play Support and Tank just yet because the team relies on them more for teamwork and I know I'll fuck it up right now.
Game feels really polished and runs smooth. I tried it on my laptop (W10, i5, dedicated card, ssd, 8GB) as well and it plays great on medium/high settings.
