It's really fun, and I was surprised to find that I enjoy playing as support a lot, my mains so far have been McCree, Mercy, Reinhardt and Bastion.
Main issue I've had is with the Road 66 map, where the attacking team is pretty much screwed, haven't been in a single match where the attacking team was able to move past their spawns, other than that, the maps are fun, the heroes are all cool and unique and I like the way it plays. \m/ \m/
