It's a lot like TF2 and isn't a very inspired game in many ways, but still retains the level of quality you would expect from blizzard. Everything about it is good, though not necessarily new or game changing. I'm having a lot of fun with it right now anyway.
Right now I've been playing a lot more Reinhardt and I'm a really fucking good reinhardt I realized. So much fun too. Probably my best champ atm, though I also like Hanzo, D.va, Roadhog, Bastion and Zenyatta.
