Overwatch was 100% a great game at one point, there was a reason it had so many players. I love Overwatch and TF2, and while they're similar conceptually, they really don't play that similarly. Especially competitively.
Yeah I enjoyed OW for a bit. Me and the gf would play mayhem mode when it was up. We stopped playing when they forced the change to OW2 and took some of the skins. I miss ow, but have no desire to play OW2.
