Blizzard's PR has been horrendous for much longer than this, but this is the most recent fuck up.
Blizzcon is going to be a hoot if Blizzard doesn't have anything good to show (they won't, they only had 1 year to try and rush out a Diablo 4 concept). They'll probably have some WoW expansion stuff but honestly I don't think they can skate by with just that.
maybe in order to satiate the masses
they will have to announce that 2 overwatch characters are now alphabet people
